Question 86911
{{{(12x^2+4x-1)/(2x+1)}}}


{{{(2x+1)(6x-1)/(2x+1)}}} Factor the numerator (note: if you need help with factoring, check out this <a href=http://www.algebra.com/algebra/homework/Polynomials-and-rational-expressions/quadratic-factoring.solver>solver</a>)


{{{cross((2x+1))(6x-1)/cross((2x+1))}}} Cancel like terms


So it simplifies to this:

{{{6x-1}}}

{{{(x^2+3x-4)/(x^2-x-20)}}}


{{{(x+4)(x-1)/(x^2-x-20)}}} Factor the numerator


{{{(x+4)(x-1)/(x-5)(x+4)}}} Factor the denominator


{{{cross((x+4))(x-1)/(x-5)cross((x+4))}}} Cancel like terms


So it simplifies to this:

{{{(x-1)/(x-5)}}}
