Simplifying Rational Expression?
The Question is:
6a^2 - 15a / 6a - 15a^2
Basically as far as I got was factoring 'a' from the numerator and denominator to get
a(6a-15) / a(6-15a)
but now I'm confused because I can't cancel the top and bottom term, if you could explain that would be really helpful... could you help me out? Thanks :)

There are other common factors, so I wouldn't factor out just 'a.'
= 3a(2a - 5) / 3a(2 - 5a) ..... cancel out the (3a) terms.
= (2a - 5) / (2 - 5a).
That is the simplest form you can get.
