Answer:
A function's zeros can be determined by setting each linear factor equal to 0 and solving.
Step-by-step explanation:
This is because in finding the zero's of a quadratic function, we factorize the quadratic function to obtain its linear factors. Then, each linear factor is then equated to zero to solve for the zeros of the quadratic function.
The solution of the equating to zero of the linear factors give the zeros of the quadratic function.
