You can put this solution on YOUR website! I will edit this problem to be x^2-5x+20=0, since that can be graphed and roots may be found. The equation as written can only be substituted for y or for x.
Large positive constant suggests complex roots
quadratic formula
x= (1/2) {5 +/- sqrt (25-80)} sqrt = -55 = i sqrt(55)
x= (1/2) * (5 +/- i sqrt (55) ) Graph will show no crossing of x-axix, parabola, with vertex at x=(5/2)
