Solution for x^2+x-198=0 equation:



x^2+x-198=0
a = 1; b = 1; c = -198;
Δ = b2-4ac
Δ = 12-4·1·(-198)
Δ = 793
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{-(1)-\sqrt{793}}{2*1}=\frac{-1-\sqrt{793}}{2} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{793}}{2*1}=\frac{-1+\sqrt{793}}{2} $
