X/3+3/4
3X/4-3/5
------------------------------
(X/3)(3X/4)+(3/4)(3X/4)-(X/3)(-3/5)+(3/4)(-3/5) NOW MULTIPLY ALL FACTORS.
3X^2/12+9X/16+3X/15-9/20
3X^2/12+(9X*15+3X*16)/(15*16)-9/20
3X^2/12+(135X+48X)/240-9/20
3X^2/12+183X/240-9/20 NOW FACTOR OUT 1/4
1/4(3X^2/3+183X/60-9/5) NOW ELIMINATE THE 3'S FROM THE FIRST TERM UNDER THE ().
1/4(X^2+183X/60-9/5)
