Question

Give the zeros (if any) of the quadratic function f(x)=3(x-4)(x+11).

Answer 1

Set each of the binomials equal to zero and solve for x. The two values will be the zeros of the equation:
(x-4) = 0      (x+11) = 0

x-4 = 0         x + 11 = 0
x = 4            x = -11

The zeros of the equation are -11 and 4
