a = 48; b = -2.38; c = -2.38;
Δ = b2-4ac
Δ = -2.382-4·48·(-2.38)
Δ = 462.6244
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{-(-2.38)-\sqrt{462.6244}}{2*48}=\frac{2.38-\sqrt{462.6244}}{96}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-2.38)+\sqrt{462.6244}}{2*48}=\frac{2.38+\sqrt{462.6244}}{96}
