I need to write a polynomial in SIMPLEST FORM having roots 2,2 and 4. I have to gt rid of the parentheses by multiplying everything out.Did I do it correctly?
(x2)(x+2)(x4)original problem
1.x^2 + 2x2x=x^24)
2. (x^24)(x4)
3. x^34x^24x+16=0

the first step should be x^2+2x2x4 = x^24(I forgot to put the (4)

So far, so good.
(x^24)(x4) = x^3  4x^2  4x + 16
You don't need an equation, just the polynomial.

Is that in simplest form or am I suppose to do something else with it? It seems too easy
