First factor the numerator
ERROR Algebra::Solver::Engine::invoke_solver_noengine: solver not defined for name 'quadratic_factoring'.
Error occurred executing solver 'quadratic_factoring' .


So our numerator becomes
%28%282x%2B1%29%286x-5%29%29%2F%288x%5E2-6x-5%29
Now factor the denominator
ERROR Algebra::Solver::Engine::invoke_solver_noengine: solver not defined for name 'quadratic_factoring'.
Error occurred executing solver 'quadratic_factoring' .


So our denominator becomes
%28%282x%2B1%29%286x-5%29%29%2F%28%282x%2B1%29%284x-5%29%29
%28cross%282x%2B1%29%286x-5%29%29%2F%28cross%282x%2B1%29%284x-5%29%29 cancel like terms
%286x-5%29%2F%284x-5%29 Here's the simplified result
