2,000=1.43x^2

Solution for 2,000=1.43x^2 equation:

2.000=1.43x^2

We move all terms to the left:

2.000-(1.43x^2)=0

We add all the numbers together, and all the variables

-(1.43x^2)+2=0

We get rid of parentheses

-1.43x^2+2=0

a = -1.43; b = 0; c = +2;
Δ = b2-4ac
Δ = 02-4·(-1.43)·2
Δ = 11.44
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{11.44}}{2*-1.43}=\frac{0-\sqrt{11.44}}{-2.86}
=-\frac{\sqrt{}}{-2.86}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{11.44}}{2*-1.43}=\frac{0+\sqrt{11.44}}{-2.86}
=\frac{\sqrt{}}{-2.86}
