Question

simplify....heres an attachment

Answer 1

First make them have common denominators, then add. Simplifying after that should be simple.

Answer 2

The common denom will be \[\large x^2\cdot7x = 7x^3\]
You can obtain it by using the good ol' "multiply by ONE" trick:

\[\huge \frac{x+2}{x^2}\cdot\left(\frac{7x}{7x}\right) +\frac{x+8}{7x}\cdot\left(\frac{x^2}{x^2}\right)\]

Hope this helps.

Answer 3

Just to improve on the above answer, a simpler common denominator is 7x^2

Answer 4

good observation, strobe. (also re: the debate thing -- if I'm shown to be wrong or incorrect, I fess up and admit it instead of 'agreeing to disagree'.) :-p

Answer 5

I ended up getting (8x^2 +10)/(7x^2).....but I dont think its right

Answer 6

Not quite, give it another go!

Answer 7

mhhh im not getting it
