What is the answer in the picture above

To solve this you must isolate x. First add 1 to both sides

x² - 1 + 1 = 0 + 1

x² = 1

Now you must take the square root of both sides to cancel out the square from the x

√x² = √1

x = 1 and x = -1

When you take the square root of a number you must remember to take both the positive and negative of the number

Hope this helped!
