x^2+2x+63=180

Solution for x^2+2x+63=180 equation:

x^2+2x+63=180

We move all terms to the left:

x^2+2x+63-(180)=0

We add all the numbers together, and all the variables

x^2+2x-117=0

a = 1; b = 2; c = -117;
Δ = b2-4ac
Δ = 22-4·1·(-117)
Δ = 472
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{472}=\sqrt{4*118}=\sqrt{4}*\sqrt{118}=2\sqrt{118}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(2)-2\sqrt{118}}{2*1}=\frac{-2-2\sqrt{118}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+2\sqrt{118}}{2*1}=\frac{-2+2\sqrt{118}}{2}
