Δ = b2-4ac
Δ = -12-4·(-1)·182
Δ = 729
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{729}=27$
$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-1)-27}{2*-1}=\frac{-26}{-2} =+13 $
$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-1)+27}{2*-1}=\frac{28}{-2} =-14 $
