Math, please help

1)Determine the equation of the polynomial function of degree 3, with zeros 2, 1, and 4. The graph of this function passes through (5, 84).
I have no idea how to do this one.
2) When 4x^4  a5x^2 + px + 6 is divided by 2x+1, the remainder is 2. Determine the value of p.

1) y= (x+2)(x+1)(x4) wouldn't that work? some might want you to multiply it out.
2) Divide the polynomial by x+1/2. See if that helps
