Find the Domain x^2+(2a+1)x^2+(a^2+2a-1)x+(a^2-1)

Problem

x2+(2*a+1)*x2+(a2+2*a−1)*x+(a2−1)

Solution

1. Identify the type of expression provided. The expression is a polynomial in terms of x where a is treated as a constant.

2. Recall the definition of the domain for polynomial functions. A polynomial is defined for all real numbers because there are no denominators that could be zero and no even roots of negative numbers.

3. Determine the set of all possible input values for x Since there are no restrictions on the variable x in a polynomial expression, the domain is all real numbers.

Final Answer

Domain:(−∞,∞)
