(1/x-4)-(4/x+7)=11/x*x+3x-28
We move all terms to the left:
(1/x-4)-(4/x+7)-(11/x*x+3x-28)=0
Domain of the equation: x-4)!=0
x∈R
Domain of the equation: x+7)!=0
x∈R
Domain of the equation: x*x+3x-28)!=0We add all the numbers together, and all the variables
x∈R
(1/x-4)-(4/x+7)-(3x+11/x*x-28)=0
We get rid of parentheses
1/x-4/x-3x-11/x*x-4-7+28=0
We calculate fractions
We do not support expression: x^3
