x^2-156=0

a = 1; b = 0; c = -156;
Δ = b2-4ac
Δ = 02-4·1·(-156)
Δ = 624
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:

$\sqrt{\Delta}=\sqrt{624}=\sqrt{16*39}=\sqrt{16}*\sqrt{39}=4\sqrt{39}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{39}}{2*1}=\frac{0-4\sqrt{39}}{2}
=-\frac{4\sqrt{39}}{2}
=-2\sqrt{39}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{39}}{2*1}=\frac{0+4\sqrt{39}}{2}
=\frac{4\sqrt{39}}{2}
=2\sqrt{39}
