Question

Lyng whose zeros and Zeros: - 4, 4, 8; degree: 3 Need this in polynomial form

Answer 1

So first, let’s put this into factored form. Note, imagine as if there were an equal sign after each zero:

(x+4)(x-4)(x-8)

Expand:

x^3-8x^2-16x+128

As you can notice, the degree — as mentioned in the original question — is in fact 3. Let me know if you have further questions.
