(0,36)x2-25-1=0

Solution for (0,36)x2-25-1=0 equation:

(0.36)x2-25-1=0

We add all the numbers together, and all the variables

(0.36)x2-26=0

We multiply parentheses

0.36x^2-26=0

a = 0.36; b = 0; c = -26;
Δ = b2-4ac
Δ = 02-4·0.36·(-26)
Δ = 37.44
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{37.44}}{2*0.36}=\frac{0-\sqrt{37.44}}{0.72}
=-\frac{\sqrt{}}{0.72}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{37.44}}{2*0.36}=\frac{0+\sqrt{37.44}}{0.72}
=\frac{\sqrt{}}{0.72}
