7/(x+2)+11/(x-5)=7/(x+2)(x-5)
We move all terms to the left:
7/(x+2)+11/(x-5)-(7/(x+2)(x-5))=0
Domain of the equation: (x+2)!=0
We move all terms containing x to the left, all other terms to the right
x!=-2
x∈R
Domain of the equation: (x-5)!=0
We move all terms containing x to the left, all other terms to the right
x!=5
x∈R
Domain of the equation: (x+2)(x-5))!=0We multiply parentheses ..
x∈R
-(7/(+x^2-5x+2x-10))+7/(x+2)+11/(x-5)=0
We calculate fractions
(-(7*(x+2)*(x-5))/((+x^2-5x+2x-10))*(x+2)*x+(7*(+x^2-5x+2x-10))*x/((+x^2-5x+2x-10))*(x+2)*x+(11*(+x^2-5x+2x-10))*x/((+x^2-5x+2x-10))*(x+2)*x=0
We can not solve this equation
