How to simplify $\left(3{a}^{4}-2{a}^{2}+5a-10\right)-\left(2{a}^{4}+4{a}^{2}+5a-2\right)$?

Paxton Houston

In order to simplify
$\left(3{a}^{4}-2{a}^{2}+5a-10\right)$ - $\left(2{a}^{4}+4{a}^{2}+5a-2\right)$, we should
distribute the negative to all of $\left(2{a}^{4}+4{a}^{2}+5a-2\right)$
so - $\left(2{a}^{4}+4{a}^{2}+5a-2\right)$ is equal to -$2{a}^{4}-4{a}^{2}-5a+2$
we can take
$3{a}^{4}-2{a}^{2}+5a-10$
-$2{a}^{4}-4{a}^{2}-5a+2$
= ${a}^{4}-6{a}^{2}-8$
