Hello!
*Solve the equation:

<span>**Separating the coefficients
</span><span>a = 3, b = -7 e c = 6
</span><span>***Calculating the value of the discriminant
</span>
Δ = b² – 4ac
Δ = (-7)² – 4.3.6
Δ = 49 – 72
Δ = - 23
p.s.: <span>Δ <0. When the discriminant is less than zero, there are no real roots.</span>
