26x^2-104=0

Solution for 26x^2-104=0 equation:

26x^2-104=0

a = 26; b = 0; c = -104;
Δ = b2-4ac
Δ = 02-4·26·(-104)
Δ = 10816
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{10816}=104$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-104}{2*26}=\frac{-104}{52}
=-2
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+104}{2*26}=\frac{104}{52}
=2
