Question

(-7v^2-7v-7)-(-4v^2+4v+8)+(-3v^2+5v-9)

Answer 1

Remove the parentheses and distribute the subtraction signs to get this
−7v2+−7v+−7+4v2+−4v+−8+−3v2+5v+−9
then combine like terms

Answer 2

you try this one :)

Answer 3

-6v^2-6v-24

Answer 4

(-7v^2-7v-7)-(-4v^2+4v+8)+(-3v^2+5v-9) -- distribute through the parenthesis
-7v^2 - 7v - 7 + 4v^2 - 4v - 8 - 3v^2 + 5v - 9
now we need to gather like terms...
-7v^2 + 4v^2 - 3v^2 = -10v^2 + 4v^2 = -6v^2
-7v - 4v + 5v = -11v + 5v = -6v
-7 - 8 - 9 = - 24

now put it all together...
-6v^2 - 6v - 24......yep....you got it :)
