Chapter 6: Q8. (page 297)

Solve each equation by graphing. If exact roots cannot be found, state the consecutive integers between which the roots are located.
$x^{2} - 2 x - 24 = 0$

Short Answer

Expert verified

The solutions to the equation $x^{2} - 2 x - 24 = 0$ are $x = - 4, 6$

Step by step solution

Step 1. Given Information.

Given to solve the equation $x^{2} - 2 x - 24 = 0$ by graphing. And if the exact roots cannot be found, the consecutive integers between which the roots are located are to be determined.

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 -4 and 6.

Hence the solutions to the equation $x^{2} - 2 x - 24 = 0$ are $x = - 4, 6$ .

Step 3. Conclusion.

Therefore, the solutions to the equation $x^{2} - 2 x - 24 = 0$ are $x = - 4, 6$
