Question
Solve by factoring.See Example 1.See the Strategy for Solving Quadratic Equations by Factoring box on page 522.$$y^{2}+14 y+49=0$$
Step 1
This is because the first term $y^{2}$ and the last term $49$ are both perfect squares, and the middle term $14y$ is twice the product of the square roots of the first and last terms. Show more…
