324x^2-1=0

Solution for 324x^2-1=0 equation:

324x^2-1=0

a = 324; b = 0; c = -1;
Δ = b2-4ac
Δ = 02-4·324·(-1)
Δ = 1296
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1296}=36$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-36}{2*324}=\frac{-36}{648}
=-1/18
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+36}{2*324}=\frac{36}{648}
=1/18
