Question 1 • Algebra III A

Which function has real zeros at x = −10 and x = −6?

Answer
f
f(x) = x2 + 16x + 60
f
f(x) = x2 − 16x + 60
f
f(x) = x2 + 4x + 60
f
f(x) = x2 − 4x + 60

Explanation

A function with zeros at x = −10 and x = −6 has factors (x + 10)(x + 6). Multiplying gives x² + 16x + 60, which matches choice A.
