Find the Domain x^2+x-20=0

Problem

x2+x−20=0

Solution

1. Identify the type of expression provided. The expression x2+x−20=0 is a polynomial equation.

2. Determine the constraints for the domain. For any polynomial function or equation of the form ƒ(x)=P(x) the variable x is not restricted by denominators, square roots of negative numbers, or logarithms.

3. Conclude that since there are no operations that restrict the input values, the domain consists of all real numbers.

Final Answer

Domain=(−∞,∞)
