3y^2/3=48

Solution for 3y^2/3=48 equation:

3y^2/3=48

We move all terms to the left:

3y^2/3-(48)=0

We multiply all the terms by the denominator


3y^2-48*3=0

We add all the numbers together, and all the variables

3y^2-144=0

a = 3; b = 0; c = -144;
Δ = b2-4ac
Δ = 02-4·3·(-144)
Δ = 1728
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{1728}=\sqrt{576*3}=\sqrt{576}*\sqrt{3}=24\sqrt{3}$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-24\sqrt{3}}{2*3}=\frac{0-24\sqrt{3}}{6}
=-\frac{24\sqrt{3}}{6}
=-4\sqrt{3}
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+24\sqrt{3}}{2*3}=\frac{0+24\sqrt{3}}{6}
=\frac{24\sqrt{3}}{6}
=4\sqrt{3}
