Question

Select the correct answer. If the zeros of a quadratic function are 3 and 8, what are the factors of the function? A. (x + 8) and (x − 3) B. (x − 8) and (x + 3) C. (x + 8) and (x + 3) D. (x − 8) and (x − 3)

Answer 1

Answer:

  D.  (x − 8) and (x − 3)

Step-by-step explanation:

The only way a product is zero is if one of the factors is zero. So, a zero of the function will make a factor of the function be zero.

The zero x=3 will make the factor (x-3) = 0.

The zero x=8 will make the factor (x-8) = 0.

The factors are (x-3) and (x-8).
