The discriminant is $= 1$ $=1$

Let's rewrite the equation

$6 y^{2} + 2 = - 7 y$ $6y^2+2=-7y$

$6 y^{2} + 7 y + 2 = 0$ $6y^2+7y+2=0$

We compare this equation to

$a x^{2} + b x + c = 0$ $ax^2+bx+c=0$

The discriminant is

$Delta=b^2-4ac$

$=(7)^2-4*(6)*(2)$

$=49-48=1$

As,

$Delta>0$ , there are 2 real roots
