Final answer:
The zeros of the quadratic function y=x² + x - 20 are -5 and 4.
Step-by-step explanation:
To find the zeros of the quadratic function y=x² + x - 20, we need to solve the equation x² + x - 20 = 0. This can be done by factoring or by using the quadratic formula. Factoring the equation gives us (x+5)(x-4) = 0, which means that the zeros are x = -5 and x = 4.
