Simplifying rational expressions

**hi0** · September 9th 2010, 08:19 AM

Kind of a tough one, not sure how to start--I'm sure it's easy I just get braindead looking at this problem.

28x^6+28x^4+14x^3
------------------------------
7x^5

Simplify

Any help would be most appreciated

that's :

$\displaystyle \frac {28x^6+28x^4+14x^3}{7x^5} = \frac {7 x^3 (4x^3+4x+2) }{7x^5} = \frac {4x (x^2+1)+2}{x^2 }$

Yes, exactly.
