4x^2=326

Solution for 4x^2=326 equation:

4x^2=326

We move all terms to the left:

4x^2-(326)=0

a = 4; b = 0; c = -326;
Δ = b2-4ac
Δ = 02-4·4·(-326)
Δ = 5216
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{5216}=\sqrt{16*326}=\sqrt{16}*\sqrt{326}=4\sqrt{326}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{326}}{2*4}=\frac{0-4\sqrt{326}}{8}
=-\frac{4\sqrt{326}}{8}
=-\frac{\sqrt{326}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{326}}{2*4}=\frac{0+4\sqrt{326}}{8}
=\frac{4\sqrt{326}}{8}
=\frac{\sqrt{326}}{2}
