Question

Factor the following expression 10x^5+5x^3-14x^2-7

Answer 1

Answer:

$\left(2x^2+1\right)\left(5x^3-7\right)$

Step-by-step explanation:

$10x^5+5x^3-14x^2-7$

$\left(10x^5+5x^3\right)+\left(-14x^2-7\right)$

$-7\left(2x^2+1\right)+5x^3\left(2x^2+1\right)$

$=\left(2x^2+1\right)\left(5x^3-7\right)$
