Find the Domain a^2+3a=0

Problem

a2+3*a=0

Solution

1. Identify the type of expression. The expression a2+3*a is a polynomial.

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

3. State the domain. Since there are no restrictions on the variable a the domain is the set of all real numbers.

Final Answer

Domain: *(−∞,∞)
