(x^2/x+10) plus (14x+40/x+10)
Ok does this make since to anyone? I get mixed up when there are powers and fractions together.

Assume question should read as:-
x² / (x + 10) + (14x + 40) / (x + 10)
(x² + 14x + 40) / (x + 10)
(x + 10)(x + 4) / (x + 10)
x + 4

the answer is x+4
(x^2/x+10)+(14x+40/x+10)= (x^2+14x+40)/ (x+10)
(x^2+14x+40) is a perfect square. factors into (x+10)(x+4)
cancel x+10 in the numerator and denominator and you are left with x+4

(x^2/x+10) + (14x+40/x+10) =
(x+4)(x+10) / (x+10) =
x+4
someone beat me to it! XD
