((x-1)/3x+15))-((x+3)/(5x+25))
HOW TO SIMPLIFY THAT???
(X-1)/(3X+15) - ((X+3)/(5X+25).
LCD = (3X+15)(5X+25).
((5x+25)(x-1)-(3x+15)(x+3))/LCD,
(5x^2-5x+25x-25-3x^2-9-15x-45)/LCD,
Combine like-terms:
(2x^2+5x-79)/(3x+15)(5x+25),
(2x^2+5x-79)/(15x^2+75x+75x+375),
(2x^2+5x-79)/(15x^2+150x375),
(2x^2+5x-79)/15(x^2+10x+25),
(2x^2+5x-79)/15(x+5)(x+5).
