Question

fatore colocando em evidencia os fatores comuns
A) x²+x x(x+1)
B) x-x³+x²

Answer 1

= x² + x.(x + 1)
= x² + x² + x
= 2x² + x
= x.(2x + 1)
==============================
b)
= x - x³ + x²
= - x³ + x² + x
= x(- x² + x + 1)

Answer 2

$A)x^{2} +x (x+1)=x (x+x+1)=x (2x+1) \\ \\ B)- x^{3}+ x^{2} +x= x (- x^{2} +x+1)$
