Question

How would i do Find the zeros of the following polynomial functions. For the 4th degree polynomials the first step of factoring is provided. Factor completely and solve
y = 2x4 + 16x3 + 32x2 = 2x2(x2 + 8x + 16)

Answer 1

help please!

Answer 2

2x^2(x^2 + 8x + 16) = 0


2x^2 = 0 or x^2 + 8x + 16 = 0


2x^2 = 0 or (x+4)^2 = 0


x^2 = 0 or (x+4)^2 = 0


x = 0 or x+4 = 0


x = 0 or x = -4

Answer 3
