y=0.04/0.3^2

Solution for y=0.04/0.3^2 equation:

y=0.04/0.3^2

We move all terms to the left:

y-(0.04/0.3^2)=0

We get rid of parentheses

y-0.04/0.3^2=0

We multiply all the terms by the denominator


y*0.3^2-0.04=0

Wy multiply elements

0y^2-0.04=0

We add all the numbers together, and all the variables

y^2-0.04=0

a = 1; b = 0; c = -0.04;
Δ = b2-4ac
Δ = 02-4·1·(-0.04)
Δ = 0.16
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{0.16}}{2*1}=\frac{0-\sqrt{0.16}}{2}
=-\frac{\sqrt{}}{2}
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{0.16}}{2*1}=\frac{0+\sqrt{0.16}}{2}
=\frac{\sqrt{}}{2}
