To find: the second root of the given

Answer to Problem 54HP
Explanation of Solution
Given:
The given quadratic equation has minimum at
Calculation:
In a quadratic equation, it is known that symmetrical across its line of symmetry, which is given by
Therefore, the two roots are equidistance from the line of symmetry.
Since one root is 11 away from the line of symmetry, the other must be 11 away as well.
Hence, the second root of the given function is
