Do algebraic expressions contain at least one variable?
yes.
Two algebraic expressions are if they have the same value for all values of their variable?
They are identical or equivalent.
What does expressions contain?
Expressions have to contain numbers and letters.
What contain the same variable to the same powers?
Like terms.
Is x-x a variable expression?
Yes. It is equal to zero. Yes, mathematical expressions can contain numbers, variables, and mathematical operations but do not contain an equal sign or inequality sign.
Do algebraic expressions contain at least one variable?
yes.
What is the definition of equivalen variable expressions?
Two expressions are "equivalent" if they have the same result for any values of the variable or variables.
Terms that contain the same variable with corresponding variables raised to the same power?
Terms that contain the same variable is called "like terms".
Which term describes a fraction that has a variable or variable expression in its numeratordenominatoror both?
There is no specific name. They can be fractions which contain algebraic or trigonometric or non-integral exponential expressions.
Two algebraic expressions are if they have the same value for all values of their variable?
They are identical or equivalent.
What does expressions contain?
Expressions have to contain numbers and letters.
What contain the same variable to the same powers?
Like terms.
How do you factorise these expressions?
In the same way that you would factorise any other expressions that do not contain an equality sign depending on the expressions of which none have been given.
What are terms that contain the same variables to the same power?
Terms that contain the same variable is called "like terms".
Why are algebraic expressions called variables?
Algebraic expressions may contain variables but they are not normally called variables. In fact, if they are related to identities, they need not be variable. For example, (4x2 + 8xy + 4y2)/(x + y)2 is an algebraic expression, but it is not a variable: it equals 4.
Is x-x a variable expression?
Yes. It is equal to zero. Yes, mathematical expressions can contain numbers, variables, and mathematical operations but do not contain an equal sign or inequality sign.
What does x mean in the expression -x6?
The same as in many other expressions. It is a variable, that is, it can be replaced by any number.
