529x^2-1=0

Solution for 529x^2-1=0 equation:

529x^2-1=0

a = 529; b = 0; c = -1;
Δ = b2-4ac
Δ = 02-4·529·(-1)
Δ = 2116
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{2116}=46$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-46}{2*529}=\frac{-46}{1058}
=-1/23
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+46}{2*529}=\frac{46}{1058}
=1/23
