Find the Domain x^2-6x-27=0

Problem

x2−6*x−27=0

Solution

1. Identify the type of expression provided. The expression x2−6*x−27 is a polynomial.

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

3. State the domain in interval notation. Since there are no restrictions on the input x the domain is all real numbers.

Final Answer

Domain: *(−∞,∞)
