Question

Factorizar: xy – 2y – xz + 2z Factorizar: 2x^3+4x^4 Factorizar: x^3-x^5

Answer 1

Respuesta:

Explicación paso a paso:

1:

$xy-2y-xz+2z=y(x-2)-z(x-2)\\\\y(x-2)-z(x-2)=(x-2)(y-z)...$

2:

$2x^3+4x^4=2x^{3}(1+2x)$

3:

$x^3-x^5=x^{3} (1-x^{2} )=-x^{3} (x^{2} -1 )\\\\-x^{3} (x^{2} -1 )=(-1)x^{3} (x+1)(x-1)$
