Question

What is the solution?
1/2x^2-x+5=0

Answer 1

in other words\[\frac{ 1 }{ 2 }x^{2}-x+5=0\]
multiple choice
\[1\pm i\sqrt{11}\]
\[-1\pm i \sqrt{9}\]
\[1\pm i \sqrt{9}\]
\[-1\pm i \sqrt{11}\]

Answer 2

since you have answer choices, I would just multiply the roots (ie: (1 + isqrt(11))(1 - isqrt(11)) and see if you get the above equation. hope that helps?
