X^2+15X+37=0

a = 1; b = 15; c = +37;
Δ = b2-4ac
Δ = 152-4·1·37
Δ = 77
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{-(15)-\sqrt{77}}{2*1}=\frac{-15-\sqrt{77}}{2}
$


$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(15)+\sqrt{77}}{2*1}=\frac{-15+\sqrt{77}}{2}
$
