Chapter 7 - Polynomial Equations and Factoring - 7.4 - Solving Polynomial Equations in Factored Form - Exercises - Page 381: 23

The x-coordinates are $x=14$ and $x=5$.

The graph crosses the x-axis when $y=0$. $\implies y=-(x-14)(x-5)=0$ Using zero-product property, we have $(x-14)=0$ or $x-5=0$. Solving for $x$, we obtain $x=14$ or $x=5$. The x-coordinates are $x=14$ and $x=5$.
