If the discriminant is equal to one, then the equation has two roots.
D = b 2 4 a c = 13 2 4 3 14 = 169 168 = 1
x1= (-b + root of D) / 2a = (13+1) / 2*3 = 14 / 6 = 7/3
x2= (-b - root of D) / 2a = (13-1) / 2*3 = 12/6 = 2

Help with solution to 2 variable quadratic equation.
Could someone help with an explanation on how to treat the equation below, please? A solution I have read uses the discriminant to find the range i.e.
920y216y>or=0. To me this means treating the variable Y as a constant , is that "acceptable" ? does anyone have a reference for these equations ?
yx2+5y3x+4=0
rewrite as yx23x+(5y+4)=0
