b=82b*2b

Solution for b=82b*2b equation:

b=82b*2b

We move all terms to the left:

b-(82b*2b)=0

We add all the numbers together, and all the variables

b-(+82b*2b)=0

We get rid of parentheses

b-82b*2b=0

Wy multiply elements

-164b^2+b=0

a = -164; b = 1; c = 0;
Δ = b2-4ac
Δ = 12-4·(-164)·0
Δ = 1
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$b_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1}=1$
$b_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1)-1}{2*-164}=\frac{-2}{-328}
=1/164
$
$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+1}{2*-164}=\frac{0}{-328}
=0
