I have this equation that I have trouble comprehending the answer to it. It's been a while since I took Algebra II and this is practice in Pre Cal book. I want to be able to find out about the Lowest Common Denominator. Thanks for your help.
5 / 2x+3 + 4 / 2x-3 = 14x+3 / 4x^2-9
Please use parentheses! What you really mean is 5/(2x+3)+ 4/(2x-3)= 3/(4x^2- 9).
You can get rid of the fractions completely by multiplying each fraction by the lest common denominator. What is that least common denominator? The denominators are 2x+ 3, 2x- 3, and .
