Write as a difference of fractions

Theory

Write as a difference of fractions

If the numerator of a fraction is a difference it can be rewritten as difference of fractions. The denominator is the same, and the numerators are the terms in the difference of the original expression. This is the same rule as when subtracting fractions, but the other way around.
