Y=2E-08x^2

Solution for Y=2E-08x^2 equation:

=2-08Y^2

We move all terms to the left:

-(2-08Y^2)=0

We get rid of parentheses

08Y^2-2=0

a = 08; b = 0; c = -2;
Δ = b2-4ac
Δ = 02-4·08·(-2)
Δ = 64
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$Y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$Y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{64}=8$
$Y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-8}{2*08}=\frac{-8}{16}
=-1/2
$
$Y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+8}{2*08}=\frac{8}{16}
=1/2
