Question

Fully simplify the expression:

( 5 / x^2 ) + ( 4 / x^2+x )

Of course x^2 factors as x * x ; be sure to also factor x^2 + x when determining the least common denominator.

Answer 1

\[\frac{5}{x^{2}} + \frac{4}{x(x+1)} \]

Answer 2

\[\frac{5x^{2}+5x+4x^{2}}{x^{3}(x+1)}\]

Answer 3

you finish it, i'm lazy :)

Answer 4

ps and x on top cancels

Answer 5

So I got stuck.. after combining the top, I got (9x^2+5x)

How do I factor out the bottom? x^3(x+1)
:/

Answer 6

Never mind, got it. x^2(x+1) Thanks!
