# How do you factor the expression 20g^3+24^2-15 g-18?

Dec 22, 2015

$\left(4 {g}^{2} - 3\right) \left(5 g + 6\right)$
Assuming the expression was meant to read $20 {g}^{3} + 24 {g}^{2} - 15 g - 18$
$4 {g}^{2} \left(5 g + 6\right) - 3 \left(5 g + 6\right)$
Hence $\left(4 {g}^{2} - 3\right) \left(5 g + 6\right)$
