Solve for the variable. b^2 = 100

b = ±10

or

b = -10, 10

Step-by-step explanation:

Step 1: Write equation

b² = 100

Step 2: Solve for b

Step 3: Check

Plug in x to verify it's a solution.

(-10)² = 100

(10)² = 100

b=-10 or b=10

Step-by-step 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 :/

nope.   happens to me as well.
