(v-5)(v+3)
Is this answer correct v+15
If you have not had FOIL, use distributive property
v(v+3) - 5(v+3)
= v^2 + 3 v - 5 v - 15
= v^2 - 2 v - 15
FOIL is for doing these
First, Outer, Inner, Last
v*v + v*3 - 5*v - 5*3
Is this answer correct v+15
v(v+3) - 5(v+3)
= v^2 + 3 v - 5 v - 15
= v^2 - 2 v - 15
FOIL is for doing these
First, Outer, Inner, Last
v*v + v*3 - 5*v - 5*3
