Question 153998: I need to subtract two rational expressions, and the problem is
((3a+2b)/(3b)) - ((a+2b)/(6a))
I do not understand how to find the lowest common denominator, and what to do after I do find it. Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! ((3a+2b)/(3b))-((a+2b)/(6a))
[(3a+2b)(6a)-(a+2b)(3b)]/3b*6a
[18a^2+12ab-3ab-6b^2]/18ab
(18a^2+9ab-6b^2)/18ab
3(6a^2+3ab-2b^2)/18ab [cancel out the factor 3 from the numerator & denominator.]
(6a^2+3ab-2b^2/6ab
