Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!

Start by inverting the denominator fraction ( ) and multiplying times the numerator fraction.

Now your denominator has addition of an integer to a fraction. The LCD is , so . Replace the denominator with this new expression:

Again, invert and multiply:

Remove like terms from numerator and denominator:

or if you prefer.

Check the answer: You can't absolutely prove the answer this way, but you can get a pretty good idea of whether you did the manipulations correctly. Pick a number. Best is a small whole number other than zero or one. Let's try 2. If u is 2, then plugging 2 into the original expression should yield 2 X (2 + 1) = 6.

. You get to do the arithmetic to see if my solution is correct.
