4x*3x=192

Solution for 4x*3x=192 equation:

4x*3x=192

We move all terms to the left:

4x*3x-(192)=0

Wy multiply elements

12x^2-192=0

a = 12; b = 0; c = -192;
Δ = b2-4ac
Δ = 02-4·12·(-192)
Δ = 9216
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{9216}=96$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-96}{2*12}=\frac{-96}{24}
=-4
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+96}{2*12}=\frac{96}{24}
=4
