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.

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
Convert the mathematics formula into Qbasic formula?
Answer: In mathematics, an algebraic expression is an expression built up from integer constants, variables, and the algebraic operations (addition, subtraction, multiplication, division and exponentiation by an exponent that is a rational number).[1] For example, {\displaystyle 3x^{2}-2xy+c} is an algebraic expression. Since taking the square rootis the same as raising to the power {\displaystyle {\tfrac {1}{2}}}, {\displaystyle {\sqrt {\frac {1-x^{2}}{1+x^{2}}}}} is also an algebraic expression. By contrast, transcendental numbers like πand e are not algebraic. A rational expression is an expressionthat may be rewritten to a rational fraction by using the properties of the arithmetic operations (commutative properties and associative properties of addition and multiplication, distributive property and rules for the operations on the fractions). In other words, a rational expression is an expression which may be constructed from the variables and the constants by using only the four operations of arithmetic. Thus, {\displaystyle {\frac {3x^{2}-2xy+c}{y^{3}-1}}} is a rational expression, whereas {\displaystyle {\sqrt {\frac {1-x^{2}}{1+x^{2}}}}} is not. A rational equation is an equation in which two rational fractions (or rational expressions) of the form {\displaystyle {\frac {P(x)}{Q(x)}}} are set equal to each other. These expressions obey the same rules as fractions. The equations can be solved by cross-multiplying. Division by zero is undefined, so that a solution causing formal division by zero is rejected. answer found on Brainly by mohamedeshna747
