Question

Fatoração
3x(x - 2y)² - (x - 2y) ³

Resposta:
2(x - 2 y) ²(x+y)

Answer 1

$Resolu\c{c}\~ao \to \left\{\begin{array}{ccc}3x*(x-2y)^2-(x-2y)^3 = \\\\3x*(x-2y)^2-(x-2y)^2*(x-2y) = \\\\(x-2y)^2*[3x-(x-2y)] = \\\\(x-2y)^2*[3x-x+2y]\\\\\boxed{\boxed{(x-2y)^2*(4x+2y) \ ou \ 2*(x+y)*(x-2y)^2}}\end{array}\right$

Espero ter ajudado. =^.^=
