Answer:
v^2 - 4v - 32
Explanation:
Expand (v - 8) (v + 4) using the FOIL method.
apply the distributive property.
v (v + 4) - 8 (v + 4)
v x v + v x 4 - 8 (v + 4)
v x v + v x 4 - 8v - 8 x 4
simplify and combine like terms.
v^2 + v x 4 - 8v - 8 x 4
v^2 + 4 x v - 8v - 8 x 4
v^2 + 4v - 8v - 32
v^2 - 4v - 32
