can be solved by "completing the square"
or by using the quadratic formula.
Completing the square:
The expression becomes itself if we interchange a and b,
so it does not matter which root is and which root is .
Let us say that and .
Those are base 10 logarithms, so to get to base a and base b,
we use the "change of base formula."
.
Now we can calculate that expression
