a = 3; b = -1575; c = +2;
Δ = b2-4ac
Δ = -15752-4·3·2
Δ = 2480601
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{-(-1575)-\sqrt{2480601}}{2*3}=\frac{1575-\sqrt{2480601}}{6}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-1575)+\sqrt{2480601}}{2*3}=\frac{1575+\sqrt{2480601}}{6}
