5/2x^2=250

Solution for 5/2x^2=250 equation:

5/2x^2=250

We move all terms to the left:

5/2x^2-(250)=0


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

x^2!=0/2

x^2!=√0

x!=0

x∈R


We multiply all the terms by the denominator


-250*2x^2+5=0

Wy multiply elements

-500x^2+5=0

a = -500; b = 0; c = +5;
Δ = b2-4ac
Δ = 02-4·(-500)·5
Δ = 10000
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{10000}=100$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-100}{2*-500}=\frac{-100}{-1000}
=1/10
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+100}{2*-500}=\frac{100}{-1000}
=-1/10
