X^2-3X-118=0

a = 1; b = -3; c = -118;
Δ = b2-4ac
Δ = -32-4·1·(-118)
Δ = 481
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{-(-3)-\sqrt{481}}{2*1}=\frac{3-\sqrt{481}}{2}
$


$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-3)+\sqrt{481}}{2*1}=\frac{3+\sqrt{481}}{2}
$
