Find the Domain 2/(x-2)=8/(x+13)
Problem
Solution
Identify the denominators in the equation. The expressions in the denominators are
x−2 andx+13 Set each denominator to be non-zero, as division by zero is undefined in the set of real numbers.
Solve the first inequality
x−2≠0 to find thatx≠2 Solve the second inequality
x+13≠0 to find thatx≠−13 Combine these restrictions to define the domain as all real numbers except
x=2 andx=−13
