# How do you factor the expression 12x^4 + 10x^3 − 12x^2?

$2 {x}^{2} \left(6 {x}^{2} + 5 x - 6\right)$
$12 {x}^{4} + 10 {x}^{3} - 12 {x}^{2}$
12 and 10 are both divisible by 2, and we can take out ${x}^{2}$ out of all the exponents (since we add and subtract exponents when multiplying).
$2 {x}^{2} \left(6 {x}^{2} + 5 x - 6\right)$
