4(1/x-2)^2-(7/x-2)-2=0
Domain of the equation: x-2)^2!=0
x∈R
Domain of the equation: x-2)!=0We get rid of parentheses
x∈R
4(1/x-2)^2-7/x+2-2=0
We calculate fractions
(4(1*x)/(x-2)^2*x)+(-7x)/(x-2)^2*x)+2-2=0
We calculate terms in parentheses: +(4(1*x)/(x-2)^2*x), so:We multiply all the terms by the denominator
4(1*x)/(x-2)^2*x
We add all the numbers together, and all the variables
4(+x)/(x-2)^2*x
We multiply all the terms by the denominator
4(+x)
We multiply parentheses
4x
Back to the equation:
+(4x)
4x*(x-2)^2*x)+2-2+(-7x)=0
