Solve by extracting roots. Round your answers to two decimal places.

2.8x² = 2x² + 22.1

+ / - 5.26

Step-by-step explanation:

Subtract both sides by 2x^2

.8x^2 = 22.1

Divide by. 8

x^2 = 27.625

Take the square root on both sides

x = + / - 5.26

It's either a positive or a negative number because the sign doesn't matter when you square the number so we have to account for both possibilities.
