0=50x2-8

Solution for 0=50x2-8 equation:

0=50x^2-8

We move all terms to the left:

0-(50x^2-8)=0

We add all the numbers together, and all the variables

-(50x^2-8)=0

We get rid of parentheses

-50x^2+8=0

a = -50; b = 0; c = +8;
Δ = b2-4ac
Δ = 02-4·(-50)·8
Δ = 1600
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1600}=40$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-40}{2*-50}=\frac{-40}{-100}
=2/5
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+40}{2*-50}=\frac{40}{-100}
=-2/5
