Question

xsquared+x+1=o

Answer 1

x^2+x+1=0
it is apparent that you will have a complex number since you cannot square any "real" number add that number again and add one to it and the answer be 0.
Therefore you apply the quadratic formula:
[(-b \pm \sqrt{b^2-4ac})/(2a)\]

Answer 2

\[(-b \pm \sqrt{b^2-4ac})/(2a)\]
