Divide:
x^2 + 2x - 15 x^2 - 25
------------- / ------------
4x^2 2x - 10
:
Remember when dividing, you invert the dividing fraction, and multiply:
%28x%5E2+%2B+2x+-+15%29%2F%284x%5E2%29 * %282x+-+10%29%2F%28x%5E2+-+25%29
:
You can do some major factoring here:
%28%28x%2B5%29%28x-3%29%29%2F%284x%5E2%29 * %282%28x+-+5%29%29%2F%28%28x%2B5%29%28x-5%29%29
:
Cancel x+5, x-5, also the the 2 cancels into the 4, resulting in:
%28x-3%29%2F%282x%5E2%29
