Need help.

Please don't post "Sorry, I can't help you." or "I dunno." or etc.

Need help with Algebra. ("/" = over ^ = exponent)

Rational Functions and Expressions

2n^2- 5n -3 / 4n^2 - 12n - 7 multiplied by 2n-7 / 4n + 5

I think you have to factor the ones with the exponents in them, and then some of the stuff should cancel out.

I know, but I don't know how to factor when there's a number in front of the n^2...

I was absent when they did that lesson.

 

[Furry Sparks]

it factors to (2n + 1)(n - 3)

You just figure out out in your head, there's not really a way to do them...

 

[Bacon Boy]

thanks!

sorry, what about the second half? under the (2n+1) and (n-3)

 

[Furry Sparks]

Ahg, I forgot to say that was just the factor of the 2n^2 - 5n - 3

And don't ask me for the rest.

okay, thanks for helping.

I get:

( (2n+1)(n-3) / (2n-7)(2n+1) ) * (2n-7) / (4n+5)

After canceling stuff out, I end up with (n-3) / (4n+5)

thanks!
