Question

Find the zeros of the function.

Write the smaller solution first, and the larger solution second.
f(x) = (x – 3)(2x – 8)

Answer 1

x = 3, x = 4

Explanation:

To find the zeros of the function, equate f(x) to zero, that is

(x - 3)(2x - 8) = 0

Equate each factor to zero and solve for x

x - 3 = 0 ⇒ x = 3 ← smaller solution

2x - 8 = 0 ⇒ 2x = 8 ⇒ x = 4 ← larger solution
