0=2x^2-x+2
Use the quadratic equation:
(-b +/- squarert(b^2-4ac)) / 2a
You will find that when you work out the square root part that the stuff inside the parentheses sends up negative, and you can’t find the square root of a negative number. The answer is no solution.
[edit]
Looking above: yes, if you can factor, but in this case it is unable to be factored.

Set 2x^2-x+2 equal to zero. Factor and solve for x.
Hope this helps.

adding to what the previous answer stated, y is equal to zero when you find the x intercept.
