Explain the benefits of evaluating the discriminate of a
Answer to Problem 131AYU
Benefit to finding the discriminate is to confirm that you have the right number of solutions, if they even exist.
Explanation of Solution
Given information:
Explain the benefits of evaluating the discriminate of a quadratic equation before attempting to solve it.
Calculation:
Describe the benefits of finding the value of the discriminate of a quadratic equation before attempting to solve it.
To solve a quadratic of the form
If the value of the discriminate
It saves time to find the discriminate first because if the discriminate is negative, there is no real solution so no other calculations or factoring is necessary.
Hence, another benefit to finding the discriminate is to confirm that you have the right number of solutions, if they even exist.
