1.92=x*3X

Solution for 1.92=x*3X equation:

1.92=x*3x

We move all terms to the left:

1.92-(x*3x)=0

We add all the numbers together, and all the variables

-(+x*3x)+1.92=0

We get rid of parentheses

-x*3x+1.92=0

Wy multiply elements

-3x^2+1.92=0

a = -3; b = 0; c = +1.92;
Δ = b2-4ac
Δ = 02-4·(-3)·1.92
Δ = 23.04
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{23.04}}{2*-3}=\frac{0-\sqrt{23.04}}{-6}
=-\frac{\sqrt{}}{-6}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{23.04}}{2*-3}=\frac{0+\sqrt{23.04}}{-6}
=\frac{\sqrt{}}{-6}
