# Chapter 9 - Quadratic Functions and Equations - 9-4 Factoring to Solve Quadratic Equations - Lesson Check: 1

The solutions are 4 and 7.

#### Work Step by Step

Use the zero product property. If the product is 0, one of the factors is zero. $v-4=0$ OR $v-7=0$ $\longrightarrow$ solve for v using addition property of equality $v-4+4=0+4$ OR $v-7+7=0+7$ $v=4$ OR $v=7$
