Question

Determine the solution set of (3x + 1)2 - 100 = 0.

Answer 1

Hello, Jacob!,
Suggest writing (3x + 1)2 - 100 = 0. as (3x + 1)^2 - 100 = 0. The ^ symbol calls for exponentiation.

1. Add 100 to both sides, to move the 100 to the right side.

Answer 2

(3x + 1)^2 = 100

Answer 3

2.

Answer 4

Take the square root of both sides, remembering to put a "plus or minus" sign in front of

Answer 5

he

Answer 6

the square root of 100.

What do you have now?

This equation may have two solutions. It's important that you check them (by substitution of your result into the original equation).
