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)
===================
