x*x+x=334

Solution for x*x+x=334 equation:

x*x+x=334

We move all terms to the left:

x*x+x-(334)=0

We add all the numbers together, and all the variables

x+x*x-334=0

Wy multiply elements

x^2+x-334=0

a = 1; b = 1; c = -334;
Δ = b2-4ac
Δ = 12-4·1·(-334)
Δ = 1337
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{1337}}{2*1}=\frac{-1-\sqrt{1337}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{1337}}{2*1}=\frac{-1+\sqrt{1337}}{2}
