Question
Solve by factoring.See Example 1.See the Strategy for Solving Quadratic Equations by Factoring box on page 522.$$a^{2}-16=0$$
Step 1
The difference of squares is a special case of factoring that can be used when you have an equation in the form of \(a^{2}-b^{2}\). In this case, \(a^{2}\) is \(a^{2}\) and \(b^{2}\) is \(16\). Show more…
