576x^2-441=0

Solution for 576x^2-441=0 equation:

576x^2-441=0

a = 576; b = 0; c = -441;
Δ = b2-4ac
Δ = 02-4·576·(-441)
Δ = 1016064
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1016064}=1008$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-1008}{2*576}=\frac{-1008}{1152}
=-7/8
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+1008}{2*576}=\frac{1008}{1152}
=7/8
