Find the Domain x^2-49=0

Problem

x^2−49=0

Solution

1. Identify the type of expression. The expression x^2−49 is a polynomial.

2. Determine the domain of a polynomial. Polynomials are defined for all real numbers because there are no denominators that could be zero and no even roots of negative numbers.

3. Conclude that the domain is the set of all real numbers, regardless of the equation x^2−49=0

Final Answer

Domain: *(−∞,∞)
