64.x2-529=0

Solution for 64.x2-529=0 equation:

64.x^2-529=0

a = 64.; b = 0; c = -529;
Δ = b2-4ac
Δ = 02-4·64.·(-529)
Δ = 135424
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{135424}=368$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-368}{2*64.}=\frac{-368}{128}
=-2+7/8
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+368}{2*64.}=\frac{368}{128}
=2+7/8
