x*3x=1323

Solution for x*3x=1323 equation:

x*3x=1323

We move all terms to the left:

x*3x-(1323)=0

Wy multiply elements

3x^2-1323=0

a = 3; b = 0; c = -1323;
Δ = b2-4ac
Δ = 02-4·3·(-1323)
Δ = 15876
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{15876}=126$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-126}{2*3}=\frac{-126}{6}
=-21
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+126}{2*3}=\frac{126}{6}
=21
