The expression 5 - x(x)(x-2) will be undefined when any factor in the expression results in division by zero. This means that x cannot be equal to 0, x, or 2 for the expression to be defined. Therefore, the values of x that make the expression undefined are x = 0, x = 1, and x = 2.

BeauOh honey, let me break it down for you. The expression 5-xx(x-2) becomes undefined when x = 2. Why? Because when x = 2, you end up dividing by zero, and we all know you can't divide by zero in this math game. So, be sure to steer clear of x = 2 if you want to keep things running smoothly.
Oh, dude, you're asking about undefined expressions now? Well, when it comes to this one, you just have to remember that division by zero is a big no-no in math land. So, for this expression to be undefined, the values of x that make it happen are the ones that make the denominator (x-2) equal to zero. In this case, x = 2 would make the expression go "poof" into undefined territory.

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.
