Write the factored form of the polynomial function with real coefficients, a lead coefficient of 1, and zeros of − 2 , − 4 , 4 , and 4 .

Answer 1

f(x) = (x+2)(x+4)(x-4)^2 in factored form

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

f(x) = (x^2 +6x+8)(x^2-8x+16)

f(x) = x^4 -2x^3 -24x^2+32x + 128 in unfactored form

Answer 2

P(x) = (x + 2)(x + 4)(x - 4)²
