To find: the two real numbers with a sum of
Answer to Problem 35PPS
Explanation of Solution
Given:
The sum of two real number is
Calculation:
Represent the given condition is expressed in to standard form:
Let x be the variable for the first unknown number.
And
Therefore, according to the question,
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, the equation has the solution.
The axis of symmetric is
Now write the table for the given function.
Based on the table shown, the x-intercept indicate that one solution is between
Hence, the solution of the given equation is between
