You have to multiply the two...

zehanz · Answer

So (x+4)(2x-3)=...
Whatever it is, you can safely rule out options A and B. Why?

ok i dont know but i might one day

C

@CR-Jennifer : giving a direct answer is not very helpful...

zehanz · Answer

YOu have to FOIL (x+4)(2x-3).
FOIL means:
First: x*2x = ...
Outer: x*-3 = ...
Inner: 4*2x = ...
Last: 4*-3 = ...

anonymous · Answer

(x+4)(2x-3)=(x time 2x)+(x time (-3)+(4 time 2x) +(4 time(-3))=2x^2-3x+8x-12=2x^2+5x-12
