Find the limit as x-> -infinity for (x+(x^2+12x)^1/2)(adsbygoogle = window.adsbygoogle || []).push({});

so first of all..i multiply and divide by the conjugent then i get...

-12x/(x-(x^2+12x)^1/2)

i divide by x in both the nummerator and denominator to get ....

-12/1-(1+12/x)^1/2

so the 12/x goes to 0 and the squroot of 1 is 1 so it appears to be

-12/1-1 which is undefined....that is not right

where am i going wrong
