If one root of the equation x squared - 2x + M = 0 is - 3, then what is the value of the other root () m

If one root of the equation x squared - 2x + M = 0 is - 3, then what is the value of the other root () m

Using the Veda theorem: X1 = - 3. So x2 = 1, then M = - 3

The root of equation 4x = 3x is; the root of equation x (2x-1) = 3 (1-2x) is

0 3/4

If the root of the equation 2x-k + 5 = 0 of X is - 1, then k = ()
The solution of equation 5x-2 = 7x + 8 is?
If the values of 4Y + 8 and 8y-7 are opposite to each other, then the value of Y is?
Also: 2X-4 = 3x + 8
6x-7／4-2x-1／2=1-2x+5／3

Because the root of 2x-k + 5 = 0 is - 1, we take - 1 into the equation and get 2 × (- 1) - K + 5 = 0. The solution is k = 32.5x-2 = 7x + 85x-7x = 8 + 2-2x = 10x = - 53. Because 4Y + 8 and 8y-7 are opposite numbers, 4Y + 8 + 8y-7 = 0 (the sum of two opposite numbers equals 0) 12Y + 1 = 012y = - 1y = - 1 / 124.2x-4 = 3

English vowel pronunciation rules!
Which vowels do you pronounce in different parts of a word? I don't want to go to the dictionary every time. What's the rule?

Teach you one of the most basic methods
For some words with structure [x] [a] [x] [e] (where x is a consonant, such as P, K, etc.; a is a vowel)
For example: make, make, etc. the pronunciation of part a is often the same as that of the letter
Example: the word rate, because the first and third letters are consonants (R, t), the fourth is silent e, and the middle is a vowel, so the middle a pronunciation is / EI / (the same as a pronunciation), not / &# / or other
Of course, many words are exceptions. For example, some words derived from French (e.g. Cafe) do not meet this requirement. To be able to read at the sight of words, it really needs a large vocabulary of pronunciation experience. The above method is just a little skill to help you
It is suggested that you should get into the habit of turning over dictionaries more often. After you get into the habit, you can find the artifact skill of the words you want to find by just turning over them (like my foreign teacher performing this skill in front of us in those days, it was like a blockhouse); if it is too troublesome, you can also buy an electronic dictionary to look up words, although there are not enough examples to explain, But it's also an alternative
Pure handwriting, hope to adopt, thank you (if you call me a God, then my vanity will be able to meet the HA)!

How to pronounce the letter N? And, for example, how to pronounce "n" in the phonetic alphabet of a word?
ditto

N generally has two pronunciations, one is Pinyin n, and the other is when you read "en", you remove the vowel part and change it into ng, which is the back nasal

Y = x ^ 5 for derivative
y=x^5
y=3√x^2
Y = = x & # 178; & nbsp;, # 179; √ X & nbsp; & nbsp; to find the derivative (to process)

y=x^5
y'=5x^4
y=3√x^2
y'=(3x)'=3
y=x² ³√x
y'=[x^(2+1/3)]'=(x^(7/3))'=(7/3)x^(4/3)=(7/3)X ³√x

What does 1 / x ^ 2 equal after derivation

Solution
（1/x^2）'
=(x^(-2))'
=-2x^(-2-1)
=-2/x^3.
