Answer by solver91311(24713) (Show Source): You can put this solution on YOUR website!
There are two ways to go about this. You can use the formula for the derivative of a product:
If \ =\ g(x)\,\cdot\,h(x))
then \ =\ g'(x)h(x)\ +\ g(x)h'(x))
So if you let \ =\ 3x\ -\ 2)
and \ =\ 3x\ +\ 1)
Then
\ =\ 3(3x\ +\ 1)\ +\ 3(3x\ -\ 2)\ =\ 18x\ -\ 3)
Or you could first multiply the two denominators and then take the derivative of the resulting 2nd degree polynomial function.
\ =\ 9x^2\ -\ 3x\ -\ 2)
Hence
\ =\ 18x\ -\ 3)
Achieving the same result. Whichever seems easiest to you is the way to do it.
