2x-1=2x(2x-1)

Solution for 2x-1=2x(2x-1) equation:

2x-1=2x(2x-1)

We move all terms to the left:

2x-1-(2x(2x-1))=0


We calculate terms in parentheses: -(2x(2x-1)), so:

2x(2x-1)

We multiply parentheses

4x^2-2x

Back to the equation:

-(4x^2-2x)


We get rid of parentheses

-4x^2+2x+2x-1=0

We add all the numbers together, and all the variables

-4x^2+4x-1=0

a = -4; b = 4; c = -1;
Δ = b2-4ac
Δ = 42-4·(-4)·(-1)
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
