what is the solution
1/2x^2x+5=0
could someone please explain

I think you will find that if you mean
1/(2x^2x+5)=0
there is no solution. The graph has a horizontal asymptote at y=0, meaning it never is really 0.
If that's not what you intended, then please clarify. 
the possible answers are;
1+i sqrt 11
1+i sqrt 9
1 + i sqrt 9
1 + i sqrt 11 
i figured it out to be 1+isqrt9

1. D 2isqrt7
2. B over 4 up 2
3. B 112i
4. C 204i
5. A 31+i/26
6. B 1+isqrt9
You're welcome
