Simplify (3/x) + (3/(x+1)) - (3/(x+2))
|dw:1342158168800:dw|
What do you need to have in order to add and subtract fractions directly using the denominators?
\[\Large \frac{3}{x}+\frac{3}{x+1}-\frac{3}{x+2}\] Multiply everything by 1 in one form or another so that the denominator for all 3 fractions is (x)(x+1)(x+2).
