a = -3024; b = 3402; c = 0;
Δ = b2-4ac
Δ = 34022-4·(-3024)·0
Δ = 11573604
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{11573604}=3402$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(3402)-3402}{2*-3024}=\frac{-6804}{-6048}
=1+1/8
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(3402)+3402}{2*-3024}=\frac{0}{-6048}
=0
