You can put this solution on YOUR website! Find the LCD for the given rational expressions, and convert each rational expression into an equalivalent rational expression with the LCD as the denominator.
3/4b^2-9,2b/2b+3,-5/2b^2-3b
---------------------------
Factor each denominator:
4b^2-9 = (2b-3)(2b+3)
2b+3
2b^2-3b = b(2b-3)
----------------------
Form the LCD:
LCD = b(2b+3)(2b-3)
---------------------
Convert each fraction:
3/(4b^2-9) = [3*b]/LCD
2b/2b+3 = [2b^2(2x-3)]/LCD
-5/2b^2-3b = -5(b+3)/LCD
