9.36x2=18.72

Solution for 9.36x2=18.72 equation:

9.36x^2=18.72

We move all terms to the left:

9.36x^2-(18.72)=0

We add all the numbers together, and all the variables

9.36x^2-18.72=0

a = 9.36; b = 0; c = -18.72;
Δ = b2-4ac
Δ = 02-4·9.36·(-18.72)
Δ = 700.8768
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{700.8768}}{2*9.36}=\frac{0-\sqrt{700.8768}}{18.72}
=-\frac{\sqrt{}}{18.72}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{700.8768}}{2*9.36}=\frac{0+\sqrt{700.8768}}{18.72}
=\frac{\sqrt{}}{18.72}
