3/5x^2=6

Solution for 3/5x^2=6 equation:

3/5x^2=6

We move all terms to the left:

3/5x^2-(6)=0


Domain of the equation: 5x^2!=0

x^2!=0/5

x^2!=√0

x!=0

x∈R


We multiply all the terms by the denominator


-6*5x^2+3=0

Wy multiply elements

-30x^2+3=0

a = -30; b = 0; c = +3;
Δ = b2-4ac
Δ = 02-4·(-30)·3
Δ = 360
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:

$\sqrt{\Delta}=\sqrt{360}=\sqrt{36*10}=\sqrt{36}*\sqrt{10}=6\sqrt{10}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-6\sqrt{10}}{2*-30}=\frac{0-6\sqrt{10}}{-60}
=-\frac{6\sqrt{10}}{-60}
=-\frac{\sqrt{10}}{-10}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+6\sqrt{10}}{2*-30}=\frac{0+6\sqrt{10}}{-60}
=\frac{6\sqrt{10}}{-60}
=\frac{\sqrt{10}}{-10}
