Answer to Problem 44PPS
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, there is one zero in the function which is
Hence, the solution of the given equation is between
