Question 326820
{{{((6x^2-x-2)/(12x^2+5x-2))*((8x^2-6x+1)/(4x^2-1))}}}
factor what you can
{{{((6(x-2/3)(x+1/2))/(12(x-1/4)(x+2/3)))*((8(x^2-(3/4)x+1/8))/(4(x-1/2)(x+1/2)))}}}
reduce the numbers 6/12=1/2 and 8/4=2/1
{{{((1(x-2/3)(x+1/2))/(2(x-1/4)(x+2/3)))*((2(x^2-(3/4)x+1/8))/(1(x-1/2)(x+1/2)))}}}
cross cancel through multiplying fractions 
{{{(((x-2/3)(x+1/2))/((x-1/4)(x+2/3)))*(((x^2-(3/4)x+1/8))/((x-1/2)(x+1/2)))}}}
cross cancel through multiplying fractions 
{{{((x-2/3)/((x-1/4)(x+2/3)))*(((x^2-(3/4)x+1/8))/(x-1/2))}}}
