(0.25)x2=4.08

Solution for (0.25)x2=4.08 equation:

(0.25)x2=4.08

We move all terms to the left:

(0.25)x2-(4.08)=0

We add all the numbers together, and all the variables

(0.25)x2-4.08=0

We multiply parentheses

0.25x^2-4.08=0

a = 0.25; b = 0; c = -4.08;
Δ = b2-4ac
Δ = 02-4·0.25·(-4.08)
Δ = 4.08
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{4.08}}{2*0.25}=\frac{0-\sqrt{4.08}}{0.5}
=-\frac{\sqrt{}}{0.5}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{4.08}}{2*0.25}=\frac{0+\sqrt{4.08}}{0.5}
=\frac{\sqrt{}}{0.5}
