108x^2-108=0

Solution for 108x^2-108=0 equation:

108x^2-108=0

a = 108; b = 0; c = -108;
Δ = b2-4ac
Δ = 02-4·108·(-108)
Δ = 46656
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{46656}=216$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-216}{2*108}=\frac{-216}{216}
=-1
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+216}{2*108}=\frac{216}{216}
=1
