The denominator of the first expression can be factorised as follows: 2x^2 - 5x - 3 = (2x + 1)(x - 3) Can you find the lowest common denominator now?
OpenStudy (anonymous):

OpenStudy (kropot72):
I gave it already: (2x + 1)(x - 3)
OpenStudy (anonymous):
See? Thank you.
OpenStudy (kropot72):
You're welcome :)
