To solve: the given equation. If exact roots cannot be found, state the consecutive integers between which the roots are located.

Answer to Problem 27PPS
Explanation of Solution
Given:
The given equation is
Calculation:
The given equation is expressed as
Now, graph the related quadratic function to show that x-intercept of the graph. Therefore,
Looking at the graph, the parabola crosses the x-axis, therefore, there is two real solution for the graph.
The axis of symmetric is
Now write the table for the given function.
Based on the table and the graph, the x-intercept of the graph indicate that one solution is between
Hence, the solution of the given equation is between
