Question

F(x) = (x – 4)(x + 2)?
X intercept

Answer 1

`x = 4,-2`

Explanation:

Step 1: Set each factor to zero then solve

x - 4 = 0

Add 4 to both sides to get x by itself

`x - 4 + 4 = 0 + 4`

`x = 4`

x + 2 = 0

Subtract 2 to both sides to get x by itself

`x + 2 - 2 = 0 - 2`

`x = -2`

Answer:
`x = 4,-2`
