2/6x-1/3x=2/5
We move all terms to the left:
2/6x-1/3x-(2/5)=0
Domain of the equation: 6x!=0
x!=0/6
x!=0
x∈R
Domain of the equation: 3x!=0We add all the numbers together, and all the variables
x!=0/3
x!=0
x∈R
2/6x-1/3x-(+2/5)=0
We get rid of parentheses
2/6x-1/3x-2/5=0
We calculate fractions
(-108x^2)/450x^2+150x/450x^2+(-150x)/450x^2=0
We multiply all the terms by the denominator
(-108x^2)+150x+(-150x)=0
We get rid of parentheses
-108x^2+150x-150x=0
We add all the numbers together, and all the variables
-108x^2=0
a = -108; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·(-108)·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
