4x(2/3+Y)=16/3

Solution for 4x(2/3+Y)=16/3 equation:

4x(2/3+)=16/3

We move all terms to the left:

4x(2/3+)-(16/3)=0

We add all the numbers together, and all the variables

4x(+2/3)-(+16/3)=0

We multiply parentheses

8x^2-(+16/3)=0

We get rid of parentheses

8x^2-16/3=0

We multiply all the terms by the denominator


8x^2*3-16=0

Wy multiply elements

24x^2-16=0

a = 24; b = 0; c = -16;
Δ = b2-4ac
Δ = 02-4·24·(-16)
Δ = 1536
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:

$\sqrt{\Delta}=\sqrt{1536}=\sqrt{256*6}=\sqrt{256}*\sqrt{6}=16\sqrt{6}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-16\sqrt{6}}{2*24}=\frac{0-16\sqrt{6}}{48}
=-\frac{16\sqrt{6}}{48}
=-\frac{\sqrt{6}}{3}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+16\sqrt{6}}{2*24}=\frac{0+16\sqrt{6}}{48}
=\frac{16\sqrt{6}}{48}
=\frac{\sqrt{6}}{3}
