How to simplify ?
I'm given this algebraic fraction, and I'm asked to simplify it as much as possible:
I applied Ruffini's Rule to find the roots of both the Numerator and Denominator. This helped me simplify the fraction to:
I tried to further simplify the factor , to no avail. I tried these two techniques:
1. I tried to find any possible roots, but neither nor are roots.
2. I tried to see if that is a perfect square in the form: , but it isn't.
I'm not aware of any other way/technique that helps me simplify that expression. I'd just need a bit of your help. Thanks!
