Best ResponseYou've already chosen the best response.1to combine those, multiply both of them by a ratio of the common denominator, (2x + 3)(x+2)

Best ResponseYou've already chosen the best response.1THe common denominator is (2x+3)(x+3), Just multiplied the original expression by 1, the common denominator over itself

Best ResponseYou've already chosen the best response.0What does that do to add them together?

Best ResponseYou've already chosen the best response.1When you multiply that out, both will be over the same denominator, so you can add them together

Best ResponseYou've already chosen the best response.1\[\frac{ (x+9)(x+2) }{ (2x+3)(x+2) }+\frac{ (x+4)(2x+3) }{ (2x+3)(x+2) }\]

Best ResponseYou've already chosen the best response.0okay, so when you have the same denominator you just add the numerators together,correct?

Best ResponseYou've already chosen the best response.1right, you need the same denominators

Best ResponseYou've already chosen the best response.1oh k, yeah you can try expanding everything out and combining like terms in the numerator too.

Best ResponseYou've already chosen the best response.0would the numerator be 2x+13?

Best ResponseYou've already chosen the best response.1Reason i said leave the denominator, sometimes the numerator will give a factor that will cancel

Best ResponseYou've already chosen the best response.1the numerator goes to \[x^2+11x+18+2x^2+3x+8x+12\] then just combine

Best ResponseYou've already chosen the best response.0yes, one question though.. If this were subtraction how would it change what you did?

Best ResponseYou've already chosen the best response.1\[\frac{ (x+9)(x+2)(x+4)(2x+3) }{ (2x+3)(x+2) }\] it would change the sign on all the terms that are expanded (1)(x+4)(2x+3)

Best ResponseYou've already chosen the best response.1 (2x^2 +11x + 12) 2x^2  11x  12

Best ResponseYou've already chosen the best response.0it wouldn't change what you did to the denominator?
