REMEMBER: Cancellation is done after both numerator
and denominator have been completely factorized.

When denominators differ only by sign, we can make them equal by changing the sign of the numerator.
The denominator is changed to -1(b – 2) by factoring out -1.
The numerator –a is changed to a and the denominators are now the same.
