How do you find the dimensions of a polynomial?
It is the highest power of the variable in the expression.
What does it mean to solve a polynomial?
Find values of the variable for which the value of the polynomial is zero.
What does it mean to evalutate the expression?
Replace each variable in the expression by its value and then find the value of the expression.
How do you find the value of an algebraic expression?
Take the value of each variable in the expression and replace the variable by its value. Then do the math!
What is it called to find the value of a mathematical expression?
It is called "to evaluate" the expression.

To find the value of an expression you need to?
to find the value of an expression, you need to
What is it called to find the value of an algebraic expression?
To find the value of an algebraic expression is to evaluate it.
When you find the numerical value of an expression you what the expression?
You evaluate the expression !! :)

How do you find the excluded value when there isn't a variable in the denominator?
There could be a variable in the numerator which is not defined. For example, [tan(x)]/3 has no variable in the denominator but the expression is not defined for x = pi/2, for example (90 deg).
What is it called to find the value of a mathematical expression?
It is called "to evaluate" the expression.
What is it called when you find the numerical value of an expression?
You cannot find the answer to an expression!!! An expression needs to be EQUATED' to a value, for another value to be found. 2x^(2) + 5x + 12 is an EXPRESSION. Impossible to find an value for 'x'. However, 2x^(2) + 5x + 12 = 0 is an EQUATION and a result can be calculated.
How do you find the excluded values for the equation a 3 - 2a?
It is not possible to answer the question since no equation is given in the question: only an expression.
How do you find the excluded values of variables?
you put the fraction in simplest form (the numerator and denominator have no common factors besides one) then you find what number your variable should be to make the denominator 0. this is excluded value b/c your denominator can never equal 0 the number you found is your excluded value ex. 4 ------ Your excluded value is 3 because 3(3-3)=0 x(x-3)
