3x*4x=2000000

Solution for 3x*4x=2000000 equation:

3x*4x=2000000

We move all terms to the left:

3x*4x-(2000000)=0

Wy multiply elements

12x^2-2000000=0

a = 12; b = 0; c = -2000000;
Δ = b2-4ac
Δ = 02-4·12·(-2000000)
Δ = 96000000
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{96000000}=\sqrt{16000000*6}=\sqrt{16000000}*\sqrt{6}=4000\sqrt{6}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4000\sqrt{6}}{2*12}=\frac{0-4000\sqrt{6}}{24}
=-\frac{4000\sqrt{6}}{24}
=-\frac{500\sqrt{6}}{3}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4000\sqrt{6}}{2*12}=\frac{0+4000\sqrt{6}}{24}
=\frac{4000\sqrt{6}}{24}
=\frac{500\sqrt{6}}{3}
