It simplifies down to this: x2+3x(x2)(x1)

Explanation:

First things first, we have to find a common denominator by finding the least common multiple. In this case, the least common multiple of both the fractions is (x2)(x1), and therefore will serve as our common denominator. Go ahead and multiply the fractions respectively to get to the common denominator.

x(x1)(x2)(x1)2x(x2)(x1)(x2)

Now multiply the numerators out to simplify each fraction:

x2x(x2)(x1)2x24x(x2)(x1)

Make it all one fraction:

(x2x)(2x24x)(x2)(x1)

Combine like terms:

x2+3x(x2)(x1)

And you're done! Hope this helps!!!
