\(x^2-4x+4=0\\ \Rightarrow\left(x-2\right)^2=0\\ \Rightarrow x-2=0\\ \Rightarrow x=2\)
\(x^2-4x+4=0\\ \Rightarrow\left(x-2\right)^2=0\\ \Rightarrow x-2=0\\ \Rightarrow x=2\)
Tìm x biết:
a. x3 – 25x = 0 b. 3x(x- 2) – x + 2 = 0
c. x2 – 4x - 5 = 0 d.x3 – x2 + 3x – 3 = 0
e. x3 + 27 + ( x + 3)( x – 9) = 0
Tìm x:
4x(x - 2) + 3x - 6 = 0
Tìm x biết:
a)(x^2+x)^2-14.(x^2+x)+24=0
b)(x^2+x)^2+4x^2+4x-12=0
c)x^4+2x^3+5x^2+4x-12=0
d)(x+1)(x+2)(x+3)(x+4)+1=0
Please giúp mình nhé!
(x-3)^3 +(x+3)^3=0
(x+1)^3-(x-1)^3=0
x^2-4x+3=0
4x^2 +4x +1=0
(x+2)^2-(x+3)^2=0
Tìm x 4(2x + 1)² + (4x + 2)(2−6x) + (3x −1)² = 0
tìm x biết : x^3 - 4x^2 -9x +36 =0
Tìm x, biết:
x3+4x=0
Tìm x biết:
( 12x3 - 8x) : x- 4x(3x - 1) =0
Tìm x,y biết \(x^2+y^2-4x+6y+13=0\)
