Solve 2x² = 72 for x.

72

Step-by-step explanation:

Divide x2 x 2 by 1 1. Divide 72 72 by 2 2. Take the square root of both sides of the equation to eliminate the exponent on the left side. The complete solution is the result of both the positive and negative portions of the solution.

The answer is 6. Decide both sides by two which gets you x squared equals 36 and then take the square root which gets you x equals 6
