Question

resolver x
(x-2)² = (x-1)(x-2)

Answer 1

Explicación paso a paso:

x^2-4x+4=x^2-2x-x+2

x^2-4x+4=x^2-3x+2

Simplificas los "x^2"

.....-4x+4=-3x+2

Entonces: x=2 ;)

Recuerda:

(a-b)=a^2-2ab+b^2 ;)

Answer 2

x^2 - 4x + 4 = x^2 - 2x - x + 2

x^2 -4 x + 4 = x^2 - 3x + 2

Simplificas x^2

- 4x + 4 = - 3x + 2

           x = 2
