Answer :
Answer: 3x^3 - 6x - 4
Explanation
Add the expressions and combine like terms.
For example, one pair of like terms are -7x and x which combine to -6x.
Like terms are when you have the same variable and same exponent.
Answer:
f(x) + g(x) = 3x³ - 6x - 4
Step-by-step explanation:
f(x) = 8x³ - 7x + 4
g(x) = -5x³ + x - 8
f(x) + g(x) = 8x³ - 7x + 4 - 5x³ + x - 8
= 8x³ - 5x³ - 7x + x + 4 - 8
= 3x³ - 6x - 4
