A response to this same question was already given, but you should first simplify the equation into x%5E2-3x%2B4=0. Not factorable. Use general solution, or, if you want, complete the square to help put into a form for easier graphing.

Discriminant is %28-3%29%5E2-4%2A1%2A4=9-16=-6%3C0. This means that the function has no x-intercepts. NO REAL ZEROS.
