You can put this solution on YOUR website! Find the LCD for the given rational expressions, and convert each rational expression into an equivalent rational expression with the LCD as the denominator.
64. 4/x-y, 5x/2y-2x
Rewrite:
4/(x-y) , 5x/(-2(x-y))
LCD = -2(x-y)
====================
70. 3/4b2 – 9, 2b/2b+ 3, -5/2b2 – 3b
Rewrite:
3/[2b-3)(2b+3)] , 2b/(2b+3), -5/[b(b-3)]
LCD = b(2b-3)(2b+3)
===================
