Question 319682: Simplify
(2x-3)(x^2+19)^21
__________________
(3-2x)(x^2+19)^22
The answer I think is correct is:
2(x^23+19^21)
_____________
-2(x^24+19^22)
Is this correct? I'm thrown off by switching the 3-2x in the denominator to cancel out the 2x-3 in the numerator...

Also, remember that a%5Ex%2Fa%5Ey=a%5E%28x-y%29. So


Basically, %28%28x%5E2%2B19%29%5E21%29%2F%28%28x%5E2%2B19%29%5E22%29=1%2F%28x%5E2%2B19%29
