To find the polynomial function, assume that the constant is 1. Multiply the above factors and simplify. f(x) = (x - 0)(x + 6) Note that this function is one of many correct answers. Multiplying the function by any real nonzero constant will maintain the same zeros. Solution f (x) = (x – 0) (x + 6)= x(x+6) = x2 + 6x.
