a(2)=3.14(36)

Solution for a(2)=3.14(36) equation:

a(2)=3.14(36)

We move all terms to the left:

a(2)-(3.14(36))=0

We add all the numbers together, and all the variables

a^2-3.1436=0

a = 1; b = 0; c = -3.1436;
Δ = b2-4ac
Δ = 02-4·1·(-3.1436)
Δ = 12.5744
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$a_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-\sqrt{12.5744}}{2*1}=\frac{0-\sqrt{12.5744}}{2}
=-\frac{\sqrt{}}{2}
$
$a_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+\sqrt{12.5744}}{2*1}=\frac{0+\sqrt{12.5744}}{2}
=\frac{\sqrt{}}{2}
