4x=2x/x-2
We move all terms to the left:
4x-(2x/x-2)=0
Domain of the equation: x-2)!=0We get rid of parentheses
x∈R
4x-2x/x+2=0
We multiply all the terms by the denominator
4x*x-2x+2*x=0
We add all the numbers together, and all the variables
4x*x=0
Wy multiply elements
4x^2=0
a = 4; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·4·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
