$\left(-t^4-5t^3-10t^2\right)+\left(9t^3+3t^2-1\right)=-t^4+4t^3-7t^2-1$

Step-by-step explanation:

Given the expression

$\left(-t^4\:-5t^3\:-10t^2\:\right)+\left(9t^3\:+3t^2\:-1\right)$

Remove parentheses: (a)=a

=-t^4-5t^3-10t^2+9t^3+3t^2-1

Group like terms

=-t^4-5t^3+9t^3-10t^2+3t^2-1

Add similar elements

=-t^4-5t^3+9t^3-7t^2-1 ∵ -10t^2+3t^2=-7t^2

Add similar elements

=-t^4+4t^3-7t^2-1 ∵ -5t^3+9t^3=4t^3

Thus, the equivalent expression in simplified form:

$\left(-t^4-5t^3-10t^2\right)+\left(9t^3+3t^2-1\right)=-t^4+4t^3-7t^2-1$

see below

Step-by-step explanation:

Michaels proof is incorrect

Vertical angles have to have the same vertical and are formed by the same lines.

They are essentially opposite angles made by intersecting lines

AKG and AKG are not opposite angles

AKG and BKL are vertical angles, they are opposite angles made by intersecting lines so Derrick is correct
