Find the Domain 5a^2+3a^2

Problem

5*a^2+3*a^2

Solution

1. Simplify the expression by combining like terms.

5*a^2+3*a^2=8*a^2

2. Identify the type of function represented by the expression.
   The expression 8*a^2 is a polynomial.

3. Determine any restrictions on the variable a
   Polynomials are defined for all real numbers because there are no denominators that could be zero and no even roots of negative numbers.

4. State the domain in interval notation.
   Since there are no restrictions, the domain is all real numbers.

Domain=(−∞,∞)

Final Answer

Domain of *5*a^2+3*a^2=(−∞,∞)
