5 0

Answer:

(0, - 7 )

Step-by-step explanation:

given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( \frac{x_{1}+x_{2}  }{2} , \frac{y_{1}+y_{2}  }{2} )

here (x₁, y₁ ) = (- 2, - 4 ) and (x₂, y₂ ) = (2, - 10 ) , then

midpoint = ( \frac{-2+2}{2}, \frac{-4-10}{2} ) = ( \frac{0}{2} , \frac{-14}{2} ) = (0, - 7 )

=-(4a^2)-(12ab)-(9b^2)

apply minus -  plus rules :

+(-a)=-a

Refine:
