a = 3; b = -75; c = -2;
Δ = b2-4ac
Δ = -752-4·3·(-2)
Δ = 5649
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-75)-\sqrt{5649}}{2*3}=\frac{75-\sqrt{5649}}{6}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-75)+\sqrt{5649}}{2*3}=\frac{75+\sqrt{5649}}{6}
