x^2=267

Solution for x^2=267 equation:

x^2=267

We move all terms to the left:

x^2-(267)=0

a = 1; b = 0; c = -267;
Δ = b2-4ac
Δ = 02-4·1·(-267)
Δ = 1068
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:

$\sqrt{\Delta}=\sqrt{1068}=\sqrt{4*267}=\sqrt{4}*\sqrt{267}=2\sqrt{267}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-2\sqrt{267}}{2*1}=\frac{0-2\sqrt{267}}{2}
=-\frac{2\sqrt{267}}{2}
=-\sqrt{267}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+2\sqrt{267}}{2*1}=\frac{0+2\sqrt{267}}{2}
=\frac{2\sqrt{267}}{2}
=\sqrt{267}
