Verify a Solution Check a Solution

The process of making sure a solution is correct by making sure it satisfies any and all equations and/or inequalities in a problem.

Verify that x = 3 is a solution of the equation x^{2} – 5x + 6 = 0.

To do this, substitute x = 3 into the equation.

3^{2} – 5·3 + 6 = 0? 9 – 15 + 6 = 0? 0 = 0 confirmed
