Question

a) 5x^2 - 4xy - x^2y b) 5(x - 1)^2 - (1 - x) c) -2xy - 3x^2y^2 Giúp mik nhanh vs ạ

Answer 1

b: Ta có: \(5\left(x-1\right)^2-\left(1-x\right)\)

\(=5\left(x-1\right)^2+\left(x-1\right)\)

\(=\left(x-1\right)\left(5x-5+1\right)\)

\(=\left(x-1\right)\left(5x-4\right)\)

Answer 2

a: Ta có: \(5x^2-4xy-x^2y\)

\(=x\left(5x-4y-xy\right)\)
