Question 66191
Multiply the fraction:
{{{((2x^2-x-3)/(3x^2+7x+4))*((3x^2-11x-20)/(4x^2-9))}}}
Factor everything, then cancel any matching numerators and denominators.
{{{((2x^2+2x-3x-3)/(3x^2+3x+4x+4))*((3x^2-15x+4x-20)/((2x+3)(2x-3)))}}}
{{{(2x(x+1)-3(x+1))/(3x(x+1)+4(x+1))*((3x(x-5)+4(x-5))/((2x+3)(2x-3)))}}}
{{{((2x-3)(x+1)/((3x+4)(x+1)))*((3x+4)(x-5)/((2x+3)(2x-3)))}}}
{{{(cross((2x-3))*cross((x+1))/(cross((3x+4))*cross((x+1))))*(cross((3x+4))*(x-5)/((2x+3)*cross((2x-3))))}}}
{{{highlight((x-5)/(2x+3))}}}
Happy Calculating!!!
