Question

III- Aplica factor común monomio y luego factoriza. 2p.

7ab3

– 21b

IV- Factoriza. 2p.

2m(x + 1) – 2(x + 1) + n(x + 1)​

Answer 1

Respuesta:

III.-

$2p\cdot \:7ab^3-21b$

$=14pabb^2-21b$

$=2\cdot \:7bpab^2-3\cdot \:7b$

$=7b\left(2pab^2-3\right)$

IV.-

$2m\left(x+1\right)-2\left(x+1\right)+n\left(x+1\right)$

$=2mx+2m-2\left(x+1\right)+n\left(x+1\right)$

$=2mx+2m-2x-2+n\left(x+1\right)$

$=2mx+2m-2x-2+nx+n$
