Answer by josmiceli(19441) (Show Source): You can put this solution on YOUR website!
Every term in the numerator has an in it,
so factor out an
On my calculator I did
so, I guessed that the numerator could be factored as:
This worked out exactly right, so cancelling, I get:
The solutions are:
and
and
(the negative square root)
You can check by plugging this back into original equation

Hint: Check to see if 451 is a factor of 175439.
If it is, see if you can factor the numerator.
