What polynomial has zeros at - 3, 0, 4

Since there are zeros at x = - 3, x = 0, and x = 4, it could then be said that x+3 = 0, x = 0, and

x-4 = 0. Using that information, you can multiply them out to find the polynomial:

x (x+3) (x-4) = 0

(x²+3) (x-4) = 0

x³+4x²+3x-12 = 0

So the polynomial would be x³+4x²+3x-12
