x*1.3x=1933

Solution for x*1.3x=1933 equation:

x*1.3x=1933

We move all terms to the left:

x*1.3x-(1933)=0

Wy multiply elements

x^2-1933=0

a = 1; b = 0; c = -1933;
Δ = b2-4ac
Δ = 02-4·1·(-1933)
Δ = 7732
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:

$\sqrt{\Delta}=\sqrt{7732}=\sqrt{4*1933}=\sqrt{4}*\sqrt{1933}=2\sqrt{1933}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-2\sqrt{1933}}{2*1}=\frac{0-2\sqrt{1933}}{2}
=-\frac{2\sqrt{1933}}{2}
=-\sqrt{1933}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+2\sqrt{1933}}{2*1}=\frac{0+2\sqrt{1933}}{2}
=\frac{2\sqrt{1933}}{2}
=\sqrt{1933}
