3x*4x=432

Solution for 3x*4x=432 equation:

3x*4x=432

We move all terms to the left:

3x*4x-(432)=0

Wy multiply elements

12x^2-432=0

a = 12; b = 0; c = -432;
Δ = b2-4ac
Δ = 02-4·12·(-432)
Δ = 20736
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{20736}=144$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-144}{2*12}=\frac{-144}{24}
=-6
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+144}{2*12}=\frac{144}{24}
=6
