%28x%2F3+%2B+3%2F4%29%283x%2F4-3%2F5%29
%28%284x%2B+3%2A3%29%2F%283%2A4%29%29%28%283x%2A5-3%2A4%29%2F%285%2A4%29%29
%28%28%284x%2B+9%29%2F12%29%28%2815x+-12%29%2F20%29%29...........multiply nominator by nominator, and denominator by denominator
%28%28%284x%2B+9%29%2815x+-12%29%29%2F240%29%29.............
%2860x%5E2+-+48x+%2B+135x-108%29%2F240
%2860x%5E2++%2B+87x+-+108%29%2F240....divide each term by 240
0.25x%5E2++%2B+0.36x+-+0.45
