1296-0.36x^2=0

Solution for 1296-0.36x^2=0 equation:

1296-0.36x^2=0

a = -0.36; b = 0; c = +1296;
Δ = b2-4ac
Δ = 02-4·(-0.36)·1296
Δ = 1866.24
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{1866.24}}{2*-0.36}=\frac{0-\sqrt{1866.24}}{-0.72}
=-\frac{\sqrt{}}{-0.72}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{1866.24}}{2*-0.36}=\frac{0+\sqrt{1866.24}}{-0.72}
=\frac{\sqrt{}}{-0.72}
