x^2-4x+4 plz help
urgenyt​

Answer 1

Step-by-step explanation:

$x ^ { 2 } -4x+4$

solution-

Factor the expression by grouping. First, the expression needs to be rewritten as x^{2}+ax+bx+4. To find a and b, set up a system to be solved.

$a+b=-4 ab=1\times 4=4$

$Rewrite x^{2}-4x+4 \\ as \left(x^{2}-2x\right)+\left(-2x+4\right).$

$x\left(x-2\right)-2\left(x-2\right)$

$\left(x-2\right)\left(x-2\right)$

$\left(x-2\right)^{2}$

Answer 2

x^2 -2x -2x +4

x (x-2) -2(x-2)

(x-2) (x-2)
