Wy multiply elements

182x^2-72800=0

a = 182; b = 0; c = -72800;
Δ = b2-4ac
Δ = 02-4·182·(-72800)
Δ = 52998400
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{52998400}=7280$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-7280}{2*182}=\frac{-7280}{364}
=-20
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+7280}{2*182}=\frac{7280}{364}
=20
