The simplify form of
$(3a^4 - 2a^2 +5a -10)$ - $(2a^4 +4a^2 +5a -2)$

is $a^4 -6a^2 -8$

In order to simplify
$(3a^4 - 2a^2 +5a -10)$ - $(2a^4 +4a^2 +5a -2)$ , you must

distribute the negative to all of $(2a^4 +4a^2 +5a -2)$

so - $(2a^4 +4a^2 +5a -2)$ is equal to - $2a^4 -4a^2 -5a +2$

now you take

$3a^4 - 2a^2 +5a -10$
- $2a^4 -4a^2 -5a +2$

= $a^4 -6a^2 -8$

How do you simplify (3a^4-2a^2+5a-10)-(2a^4+4a^2+5a-2)(3a^4-2a^2+5a-10)-(2a^4+4a^2+5a-2)?
