a = 1; b = 15; c = +4;
Δ = b2-4ac
Δ = 152-4·1·4
Δ = 209
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$m_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(15)-\sqrt{209}}{2*1}=\frac{-15-\sqrt{209}}{2}
$


$m_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(15)+\sqrt{209}}{2*1}=\frac{-15+\sqrt{209}}{2}
$
