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.

  • Math, please help -

    1) y= (x+2)(x+1)(x-4) wouldn't that work? some might want you to multiply it out.

    2) Divide the polynomial by x+1/2. See if that helps
