Question

Solve for the variable. b^2 = 100

Answer 1

b=-10 or b=10

Explanation:

They would both work because negative times negative is also positive so it would also work.

*someone deleted my answer to this question saying it was incorrect but it was correct :/

Answer 2

b = ±10

or

b = -10, 10

Explanation:

Step 1: Write equation

b² = 100

Step 2: Solve for b

1. Square root both sides: b = ±10

Step 3: Check

Plug in x to verify it's a solution.

(-10)² = 100

(10)² = 100
