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.

4 plus 5ix plus yi Which values of x and y would make the following expression represent a real number?
If you want to ask questions about the "following", then I suggest that you make sure that there is something that is following.
How can you make a table of values for the expression 4n plus 3?
Select a set of values for n. Usually, n takes the values 1, 2, 3, 4, ... In each case, calculate 4 times the value of n and then add 3. Each n and the associated value for 4n+3 form a row/column of the table.
How do you write 2x in verbal expression?
That is in verbal expression. x is the verbal, if you're trying to make it x times 2 in verbal expression it is as you wrote it 2x.
What can't you have in the denominator?
A zero. Zero in the denominator make the expression undefined for algebraic purposes.

How do you make an equation with an undefined slope?
undefined slope is vertical. the equation of a vertical line is x=a , where a is the x intercept
What do you mean by undefined symbol in turbo c?
An undefined symbol is where you make a reference to a symbol, but you have not yet declared and defined it.
Do you solve an expression the same way you solve an equation?
If we are talking about the algebraic expressions, then an expression can be simplified or be evaluated for specific values of its variables, while an equation need to be solved, in other words to find the values of the variables that make the equation a true statement. If we are solving an equation, then we can work in the same way that we can simplify an expression (since an equation is a statement that states that two expressions are equal), or factoring an expression.
What is zero times undefined?
logically, if any number divided by 0 is undefined, than according to reverse operation, undefined times zero should be any number which would make it undefined. 0/1 x 1/0 = 0/0 which is undefined Also, "undefined" means it's undefined. If one of the factors is not defined, then you can't very well expect the product to be defined; now can you !
For which value of x is the expression x-4 over x plus 3 undefined?
The way for a fraction to be undefined is to have the lower number to be zero. So you only look at the bottom of the fraction and find what it would take to make it equal to zero. x+3=0 You would have to subtract three from both sides and you would get x= -3. So the answer is -3.
What value of N will make 7x-39x-17 true?
The given terms of the expression can be simplified to -32x-17 and no values of x can be found because it is not an equation.
