X + 2x equals 78

twenty-six

12(2x+1)2=3．

12 (2x + 1) 2 = 3, sorting out: (2x + 1) 2 = 6, square root: 2x + 1 = ± 6, that is, 2x + 1 = 6 or 2x + 1 = - 6, solution: X1 = 6-12, X2 = - 6-12

3 / 2x squared - (- 1 / 2x squared) + (- 2x squared)

3 / 2x squared - (- 1 / 2x squared) + (- 2x squared)
=(3/2+1/2-2)x²

My yearning for junior high school life

My yearning junior high school life
Six years ago, I entered primary school with the vision of school. Six years ago, I experienced sour, sweet, bitter, spicy, all kinds of human life. I learned that people should be broad-minded, not selfish. Therefore, when I am about to enter a new learning hall, I am looking forward to a beautiful, harmonious and lively middle school life!
When I see Zheng Xiaoting and Zheng Xiaodan who have been in middle school communicating in English while playing, I feel a sense of loss. How I yearn for junior high school life. When I get to junior high school, I can learn a lot of knowledge and communicate with others in simple English just like them. How cool that feeling should be!
I yearn for junior high school life, to junior high school, left my parents, take care of their own life, study. Junior high school is also a test of our self-care life: wash their own clothes; take a bath; do many things they have not done before. By then, I will not be a bird nestling beside my parents, but has been able to find their own food
I look forward to junior high school life, is in a class, when the teacher said I don't understand the place, I raise my hand to ask the teacher questions, and freely communicate with the teacher. Hope that junior high school classroom, not as boring as those who study poor, but as interesting as those who study well. If it is really interesting, then I will take this interest to study seriously
My yearning junior high school life is in physical education class, a few of our classmates play with the teacher on the basketball court, a few of our classmates and teachers in a group, scoring the ball on the court. The following students constantly praise our wonderful goals. Instead of doing push ups on the playground and running on the track
The junior high school life that I yearn for is that under the leadership of the teacher, I go to collect specimens on the back mountain of the school, and then bring them back to the classroom to do experiments. We are doing experiments happily, and we dare to compete with the teacher for the correct way of doing experiments
The junior high school life that I yearn for is that after class, we sit on the green lawn, talk to each other, tell our ideals, tell the future we yearn for, tell our past, and then play and fight together. Although we are not children enjoying our childhood at that time, we still have to live as colorful as our childhood
In a word, the junior high school life that I yearn for is a beautiful, harmonious and lively life!

Standing in the valley of youth, watching the fresh spring quietly approaching, listening to the indulgent summer wind whistling past, the loneliness of autumn and the persistence of winter interweave, I know that I have this pure youth

I live in happiness, writing in a hurry····

I live in happiness. Life is a symphony which is sometimes high and exciting, sometimes low and gentle. The conductor is always ourselves, and the baton of life is always in our own hands! My life is immersed in happiness. Happiness, a simple word, has a heavy weight. She condenses infinite love

I live in happiness
In the past, I always complained about God. Why didn't God give me an angel like face, why didn't God give me an Einstein like brain, why didn't God give me a millionaire like rich family, why, why It wasn't until an orphanage aunt said to me, "I don't know if I'm lucky." this sentence struck my head like lightning. I really realized that I live in happiness
Compared with the orphans in the welfare home, I am much happier. They have lost their parents' love since childhood, but I grew up in their arms. When I cry, my parents will coax me with candy; when I am cold, my parents will add quilts for me; when I am sick, my parents will send me to the hospital regardless of everything; when I am sad, my parents will comfort me; when I am happy, my parents will share happiness with me; I Won't all this make me feel that I live in happiness?
Compared with those disabled people, I am much happier. I have a sound body. I can climb mountains, swim and play ball games. I can participate in all kinds of activities. I can adjust my mind and keep a healthy body and mind. Won't it make me feel that I live in happiness?
Compared with the victims in the disaster, I am much happier. At least I can still live in the world and feel the beauty of life, the sunshine and the breeze. At least I can taste delicious food and experience the love between people. Won't it make me feel that I live in happiness?
There is a good song: "friends go together all their lives, those days are no longer there. In a word, a lifetime, a lifetime of love, a cup of wine..." Friends are indispensable partners in life. They share joys and pains, bitterness and tears with each other. When they succeed, they cheer together, jump together, and be happy for each other. When they are depressed and full of melancholy, they talk with their friends, talk about their hearts, and relieve their depression. Their mood will soon be smooth. They not only solve their troubles, but also promote their understanding, For every friendship, I try my best to cherish, because I believe that the dictionary of life can not be without the word "friend"!
In fact, happiness is around us. As long as you are a conscientious person, you will find it. Wealth can not bring eternal happiness, but happiness is eternal wealth

From my personal point of view: I don't think people can be compared in this way, because whether they are orphans, disabled people or people in disaster, they are not necessarily unfortunate. Happiness and unhappiness lie in their own heart. Some people ask: Why are you always happy? That person answers: it's not that I am more happy than you, it's because I care less than you! This is the problem of people's mentality, Happiness is not a result of comparison! It comes from the purification of the soul and the promotion of the realm!
