Question 474242
When the quadratic has the form
{{{ ax^2 + bx + c }}}, the discriminant is
{{{ b^2 - 4*a*c }}}
{{{ -19x^2-2x+7=0 }}}
{{{ b = -2 }}}
{{{ a = -19 }}}
{{{ c = 7 }}}
{{{ b^2 - 4*a*c = (-2)^2 - 4*(-19)*7 }}}
{{{ b^2 - 4*a*c = 4 + 532 }}}
Discriminant = 536
The equation has 2 real solutions
