Simplify and reduce the expression to lowest terms.
%2825r%29%2F%2810r%2B3%29 - %2815r-3%29%2F%2810r%2B3%29
They have the same denominators so we can write it:
%2825r-%2815r-3%29%29%2F%2810r%2B3%29
When we remove the bracket it changes the signs because of the neg
%2825r-15r%2B3%29%2F%2810r%2B3%29 = %2810r%2B3%29%2F%2810r%2B3%29 = 1; (When denominator=numerator it's always one)
