144-(12(x)+2(216/x))=0
Domain of the equation: x))!=0We add all the numbers together, and all the variables
x!=0/1
x!=0
x∈R
-(12x+2(+216/x))+144=0
We multiply all the terms by the denominator
-(12x+2(+216+144*x))=0
We calculate terms in parentheses: -(12x+2(+216+144*x)), so:We get rid of parentheses
12x+2(+216+144*x)
We add all the numbers together, and all the variables
12x+2(144x+216)
We multiply parentheses
12x+288x+432
We add all the numbers together, and all the variables
300x+432
Back to the equation:
-(300x+432)
-300x-432=0
