b/4.8*b=b

Solution for b/4.8*b=b equation:

b/4.8b=b

We move all terms to the left:

b/4.8b-(b)=0


Domain of the equation: 4.8b!=0

b!=0/4.8

b!=0

b∈R


We add all the numbers together, and all the variables

-1b+b/4.8b=0

We multiply all the terms by the denominator


-1b*4.8b+b=0

We add all the numbers together, and all the variables

b-1b*4.8b=0

Wy multiply elements

-4b^2+b=0

a = -4; b = 1; c = 0;
Δ = b2-4ac
Δ = 12-4·(-4)·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*-4}=\frac{-2}{-8}
=1/4
$
$b_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+1}{2*-4}=\frac{0}{-8}
=0
