What is a rational algebraic expression?
A rational number is any number that can be written in the form a/b, where a and b are integers and b ≠0. it is necessary to exclude 0 because the fraction represents a ÷ b, and division by zero is undefined.A rational expression is an expression that can be written in the form P/Q where P and Q are polynomials and the value of Q is not zero.Some examples of rational expressions:-5/3; (x^2 + 1)/2; 7/(y -1); (ab)/c; [(a^2)(b]/c^2; (z^2 + 3z + 2)/ (z + 1) ect.Like a rational number, a rational expression represents a division, and so the denominator cannot be 0. A rational expression is undefined for any value of the variable that makes the denominator equal to 0. So we say that the domain for a rational expression is all real numbers except those that make the denominator equal to 0.Examples:1) x/2Since the denominator is 2, which is a constant, the expression is defined for all real number values of x.2) 2/xSince the denominator x is a variable, the expression is undefined when x = 03) 2/(x - 1)x - 1 ≠0x ≠1The domain is {x| x ≠1}. Or you can say:The expression is undefined when x = 1.4) 2/(x^2 + 1)Since the denominator never will equal to 0, the domain is all real number values of x.

When the quotient of two polynomials is 3x-2. Give an example of a rational expression that is equivalent to the binomial that has the restriction x cannot equal 4?
(x-4)(3x-2)/(x-4) is equivalent to 3x-2 except when x=4.

Is a rational number is a rational expression?
Any number that can be expressed as a fraction is a rational number otherwise it is an irrational number.
How polynomial expression is a rational expression?
A polynomial expression is considered a rational expression when it is expressed as a fraction where both the numerator and the denominator are polynomials. For example, the expression ( \frac{x^2 + 3x + 2}{x - 1} ) is a rational expression because its numerator ( x^2 + 3x + 2 ) and denominator ( x - 1 ) are both polynomials. Rational expressions can be simplified, added, or multiplied, just like rational numbers, provided that the denominator is not zero.

If the common factor x - 2 is divided out of the original expression the reduced expression will be equal to the original expression only when x does not equal?

When evaluated which expression has a result that is a rational number?
An expression produces a rational number when its value can be expressed as a fraction ( \frac{a}{b} ), where ( a ) and ( b ) are integers and ( b \neq 0 ). For example, the expression ( 3 + 2 ) evaluates to ( 5 ), which is rational, as it can be represented as ( \frac{5}{1} ). Similarly, any expression involving addition, subtraction, multiplication, or division of rational numbers (as long as division by zero is avoided) will yield a rational result.
What is the value of the rational expression 17 plus xdivided by x plus 2 when x is equal to 3?
Well that's easy put the three in place of the "X" and add or what ever it says
