Answer:
(5x-11)+(11x-63)+(2x+20)
Step-by-step explanation:
If you have to solve for it then just add all your like terms into a simplified equation. 18x-54 would be the simplified version
Answer:
8
Step-by-step explanation:
f(x)=2x^4-4x^3-11x^2+3x-6
f(-2)=2(-2)^4-4(-2)^3-11(-2)^2+3(-2)-6
f(-2)=2(16)-4(-8)-11(4)-6-6
f(-2)=32+32-44-12
f(-2)=64-44-12
f(-2)=20-12
f(-2)=8
