2x^2

Step-by-step explanation:

We could factor x^2 out of all three terms, as follows:

x^2(3 - 5 + 4), or x^2(2), or 2x^2.

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
