(2/3)x=108

Solution for (2/3)x=108 equation:

(2/3)x=108

We move all terms to the left:

(2/3)x-(108)=0


Domain of the equation: 3)x!=0

x!=0/1

x!=0

x∈R


We add all the numbers together, and all the variables

(+2/3)x-108=0

We multiply parentheses

2x^2-108=0

a = 2; b = 0; c = -108;
Δ = b2-4ac
Δ = 02-4·2·(-108)
Δ = 864
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:

$\sqrt{\Delta}=\sqrt{864}=\sqrt{144*6}=\sqrt{144}*\sqrt{6}=12\sqrt{6}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-12\sqrt{6}}{2*2}=\frac{0-12\sqrt{6}}{4}
=-\frac{12\sqrt{6}}{4}
=-3\sqrt{6}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+12\sqrt{6}}{2*2}=\frac{0+12\sqrt{6}}{4}
=\frac{12\sqrt{6}}{4}
=3\sqrt{6}
