now, for a fraction, if its denominator ever becomes 0, the fraction becomes undefined, because it'd be a division by 0.
when does that happen? let's zero out the denominator to check,
x - 2 = 0, thus x = 2
so, if "x" ever becomes 2, the fractions goes kaput.
so, that domain is all real values except that one, that makes the fraction undefined.

Answer:
Difference between algebraic expression and polynomial
Step-by-step explanation:
Algebraic expression:
- An algebraic expression is made up of variable, constants and arithmetic operators like addition, subtraction, etc.
Polynomial
- A polynomial is an expression consisting of variables and coefficients, that involves operations like addition, subtraction, multiplication.
- A polynomial cannot have negative exponential powers.
Difference between algebraic expression and polynomial
- All polynomials are algebraic expression.
- All algebraic expression cannot be polynomials.
- Polynomial must have no negative exponents.
- Polynomial does not have variable inside radical system.
Let, width = x
length = 4x
perimeter = 2(4x+x) = 60
10x = 60
x = 6
so, 4x = 24
Area would be: 24*6 = 144 cm²
