(12-x^2)/3=0

Solution for (12-x^2)/3=0 equation:

(12-x^2)/3=0

We multiply all the terms by the denominator


(12-x^2)=0

We get rid of parentheses

-x^2+12=0

We add all the numbers together, and all the variables

-1x^2+12=0

a = -1; b = 0; c = +12;
Δ = b2-4ac
Δ = 02-4·(-1)·12
Δ = 48
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:

$\sqrt{\Delta}=\sqrt{48}=\sqrt{16*3}=\sqrt{16}*\sqrt{3}=4\sqrt{3}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{3}}{2*-1}=\frac{0-4\sqrt{3}}{-2}
=-\frac{4\sqrt{3}}{-2}
=-\frac{2\sqrt{3}}{-1}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{3}}{2*-1}=\frac{0+4\sqrt{3}}{-2}
=\frac{4\sqrt{3}}{-2}
=\frac{2\sqrt{3}}{-1}
