Answer:
(-12, 0) and (5, 0)
Explanation:
f(x) = x² + 7x − 60
Here, a = 1, b = 7, c = -60. Using the AC method, we need to find factors of a×c that add up to b.
12 × -5 = -60
12 + -5 = 7
The factors are 12 and -5.
f(x) = (x + 12) (x − 5)
The zeros are:
x + 12 = 0, x − 5 = 0
x = -12, x = 5
The zeros are (-12, 0) and (5, 0).
