If it's not what You are looking for type in the equation solver your own equation and let us solve it.
x in (-oo:+oo)
x^2-((25/6)*x) = 0
x^2+(-25/6)*x = 0
x^2-25/6*x = 0
DELTA = (-25/6)^2-(0*1*4)
DELTA = 625/36
DELTA > 0
x = ((625/36)^(1/2)+25/6)/(1*2) or x = (25/6-(625/36)^(1/2))/(1*2)
x = 25/6 or x = 0
x in { 0, 25/6 }
