Answer:
f(x) = x³ − 5x² − 16x + 80
Step-by-step explanation:
The degree is 3, so there are exactly 3 zeros.
The zeros are -4, 4, and 5.
f(x) = (x + 4) (x − 4) (x − 5)
f(x) = (x² − 16) (x − 5)
f(x) = x³ − 5x² − 16x + 80

Step-by-step explanation:
Question 3
5 (k + 4) - 2k
Use distributive property of multiplication.
5k + 20 -2k
Combine like terms to get your answer.
