What is a cubic polynomial function in extended form

Question

Zeros are -6, -4, -1

Given f(-2)= -32

Answer 1

(x+6)(x+4)(x+1) = 0

(x^2+10x+24)(x+1) = 0

x^3 + 11x^2 +34x + 24 = 0

f(-2) = -30, maybe -32 is a typo?

just take each zero and change its sign, then add it to x

then multiply all 3 factors together and set them equal to zero
