form a polynomial whose real zeros are -4 0 8 with a degree of 3

Question

helps me solve the problem I am asking about, and to help me better understand what polynomials are.

Answer 1

p(x) = A[x - (-4)](x - 0)(x - 8),

 

with A real and A ≠ 0.

 

p(x) = Ax(x + 4)(x - 8)

 

You can expand this to standard form if you wish.
