Chapter 6: Q10. (page 297)

Solve each equation by graphing. If exact roots cannot be found, state the consecutive integers between which the roots are located.

25+x2+10x=0

Short Answer

Expert verified

The solution to the equation 25+x2+10x=0 is x=-5.

Step by step solution

01

Step 1. Given Information.

Given to solve the equation 25+x2+10x=0 by graphing. And if the exact roots cannot be found, the consecutive integers between which the roots are located are to be determined.

02

Step 2. Explanation.

A quadratic equation has a real solution where the graph of the related function crosses or touches the x-axis.

Graphing the given equation using graphing calculator:

From the given graph, the function crosses the x axis at -5.

Hence the solution to the equation 25+x2+10x=0is x=-5.

03

Step 3. Conclusion.

Therefore, the solution to the equation 25+x2+10x=0 is x=-5
