a = -24; b = -45; c = +4;
Δ = b2-4ac
Δ = -452-4·(-24)·4
Δ = 2409
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$p_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-45)-\sqrt{2409}}{2*-24}=\frac{45-\sqrt{2409}}{-48}
$
$p_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-45)+\sqrt{2409}}{2*-24}=\frac{45+\sqrt{2409}}{-48}
