2x*3x=180

Solution for 2x*3x=180 equation:

2x*3x=180

We move all terms to the left:

2x*3x-(180)=0

Wy multiply elements

6x^2-180=0

a = 6; b = 0; c = -180;
Δ = b2-4ac
Δ = 02-4·6·(-180)
Δ = 4320
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:

$\sqrt{\Delta}=\sqrt{4320}=\sqrt{144*30}=\sqrt{144}*\sqrt{30}=12\sqrt{30}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-12\sqrt{30}}{2*6}=\frac{0-12\sqrt{30}}{12}
=-\frac{12\sqrt{30}}{12}
=-\sqrt{30}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+12\sqrt{30}}{2*6}=\frac{0+12\sqrt{30}}{12}
=\frac{12\sqrt{30}}{12}
=\sqrt{30}
