Express your answer in simplest form;

[x^2 / x + 10] + [9x - 10 / x + 10]

next step I combined the top row together and got

x^2+9x-10

which is;

(x-1)(x+10)/x+10

Now do I cancel out the x+10

and be lefted with (x-1) as my answer???

What do you mean by "the top row"? You appear to have two expressions:

. . . . .\(\displaystyle \L \left[\frac{x^2}{x}\, +\, 10\right]\, +\, \left[9x\, -\, \frac{10}{x}\, +\, 10\right]\)

Or did you mean the following...?

. . . . .\(\displaystyle \L \left[\frac{x^2}{x\, +\, 10}\right]\, +\, \left[9x\, -\, \frac{10}{x\, +\, 10}\right]\)

...which could also be formatted as:

. . . . .[ (x^2) / (x + 10) ] + [9x - (10) / (x + 10) ]

Or did you mean something else?

(For information on standard web-safe formatting, please review the "Karl's Notes" article, following the link either in the "Forum Help" pull-down menu at the very top of this page, or else in the "Read Before Posting" thread at the top of this forum's topic listing.)

Thank you! :D

x<sup>2</sup>/(x+10) + (9x-10)/(x+10)

next step I combined the top row the numerators together and got

x^2+9x-10

which is;

(x-1)(x+10)/x+10

(x-1)(x+10)/(x+10)

yes
