Can someone help me out i really read the lesson but im still stuck! Please no big words just steps and numbers i'm very visual.... thanks :)
1.Determine the zeros of f(x) = x^3 – 3x^2 – 16x + 48.
2.Determine the zeros of f(x) = x^3 – 12x^2 + 28x – 9.
3.Determine the zeros of f(x) = x^4 – x^3 + 7x^2 – 9x – 18.
4.Find the polynomial function with roots 1, –2, and 5.
5.Find the polynomial function with roots 1, 7, and –3 of multiplicity 2.
6.Find the polynomial function with roots 11 and 2i.

1) x^2(x-3)-16(x-3) = (x-3)(x^2-16) =
(x-3)(x+4)(x-4)
Zeros are 3, 4 and -4
4) f(x) = (x-1)(x+2)(x-5)
Expand to get the function.
