**[SOLVED] Can you help me evaluate this limit?**

lim k -[tex]\sqrt{k^{2}+k}[/tex] as k[tex]\rightarrow[/tex][tex]\infty[/tex]

I have evaluated the limit using computer technology and I know it should be

-1/2. I have tried using something like the squeeze theorem but failed.

My other attempt is to mutiply the limit by the expression

lim k +[tex]\sqrt{k^{2}+k}[/tex] / lim k +[tex]\sqrt{k^{2}+k}[/tex]

Please help me. I know this is a simple problem, but I got stuck. Thank you

for your time and I hope you reply.
