Answer:
a³ + b³
Step-by-step explanation:
Given
(a + b)(a² - ab + b²)
Each term in the second factor is multiplied by each term in the first factor, that is
a(a² - ab + b²) + b(a² - ab + b²) ← distribute both parenthesis
= a³ - a²b + ab² + a²b - ab² + b³ ← collect like terms
= a³ + b³

Answer:
C 2x^2 + 3/2x -5
Step-by-step explanation:
f(x)=x/2-2
g(x)=2x^2+x-3
(f+g) (x)=x/2-2+2x^2+x-3
Combine like terms
2x^2 + 3/2x -5
I would tell you how to do it but its a very hard thing to explain
