Best ResponseYou've already chosen the best response.0is this \[ \frac{2x+5}{x^23x10} + \frac{ x+1}{x+2} \]?

Best ResponseYou've already chosen the best response.0first factor the bottom of the first fraction (to get a better idea of what is going on) \[ \frac{2x+5}{x^23x10} + \frac{ x+1}{x+2} \\ \frac{2x+5}{(x+2)(x5)} + \frac{ x+1}{x+2} \]

Best ResponseYou've already chosen the best response.0to get a common denominator, multiply the second fraction by (x5) (top and bottom) \[ \frac{2x+5}{(x+2)(x5)} + \frac{ (x+1)}{(x+2)} \frac{(x5)}{(x5)} \] now we can add the tops. First, multiply out the top of the second fraction: \[ \frac{2x+5}{(x+2)(x5)} + \frac{ x^24x5} {(x+2)(x5)}\]

Best ResponseYou've already chosen the best response.0now add the tops and put the sum over the common denominator \[\frac{ x^22x} {(x+2)(x5)}\] it looks like we can factor out an x \[ \frac{ x(x2)} {(x+2)(x5)}\] yes, it looks like the same thing as what you posted.
