Square of (x + 1) - (x + 2) (X-2)

Square of (x + 1) - (x + 2) (X-2)

(x x x 1) &# 178; - (x x x 2) (X-2) = x & # 178; + 2x + 1-x & # 178; + 4 = 2x + 5

The square of x minus 2x plus 1 equals 0. What does x equal?

X squared - 2x + 1 = 0
On the left is the expansion of the complete square
The square of (x-1) = 0
Square both sides,
x - 1 = 0
x = 1

How to calculate the square of (A-1) x + 2x + 1 > equal to 0

The classification is discussed
That is to say, the coefficient of quadratic term is negative, 0 and positive
The solution set of a is obtained
If you don't say it again

The square of 20x + x = 10
Wait online! Bonus points!
It's 21, it's not 20! Wrong!!!!
I don't understand the meaning of 1l
Number changed... Wrong number just now!

21x²+x-10=0
（3x-2）（7x+5）=0
X = 2 / 3 or x = - 5 / 7

How to solve the following equation 13.2x + 9x = 33.3x minus 0.36x = 16?

Hello
13.2x plus 9x = 33.3
22.2x=33.3
x=1.5
X minus 0.36x = 16
0.64x=16
x=16÷0.64
x=25

36x = 16

25

36x 2 16,

Hanying warm for you
（1-0.36）x =16
0.64X =16
X=25
(or click "satisfied" in the upper right corner of the client)
It's my driving force!
If you don't understand,
Until the completion of understand this problem!

X-0.36x = 16 recursive equation calculation

x-0.36x=16
0.64x=16
x=16÷0.64
x=25

(1) X △ 4.5 = 2.1 & nbsp; & nbsp; & nbsp; X △ 4.5 × 4.5 = 2.1 × 4.5 & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 9.45 substitute x = 9.45 into the original equation, left = 9.45 △ 4.5 = 2.1, right = 2.1, left = right, so x =

24x squared y * 7 / 36x squared y squared

Solution to 24x & # 178; y × (7 / 36x & # 178; Y & # 178;) - is this = (24 × 7 / 36) [x & # 178; y × (1 / X & # 178; Y & # 178;)] = 14 / (13y)
