Write a polynomial function in standard form with zeros at –4, 4, and –2

Question

f(x)=x^3-14x^2+64x-4

f(x)=x^3+2x^2-16x-4

f(x)=x^3-32x^2+2x-16

f(x)=x^3+2x^2-16x-32

Answer 1

polynomial function in standard form

f(x)=(x+4)(x-4)(x+2)

     =(x^2-16)(x+2)

    =x^3-16x+2x^2-32

    =x^3+2x^2-16x-32
