a = 3; b = 3; c = -77;
Δ = b2-4ac
Δ = 32-4·3·(-77)
Δ = 933
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(3)-\sqrt{933}}{2*3}=\frac{-3-\sqrt{933}}{6}
$


$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3)+\sqrt{933}}{2*3}=\frac{-3+\sqrt{933}}{6}
$
