A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

What does it you to evaluate an algebraic expression?

To evaluate an algebraic expression means to simplify the expression as much as possible by replacing the variables in an expression with the numerical values given to you.Ex:Example of Evaluating an Algebraic ExpressionTo evaluate the algebraic expression '4.5 + x' for x = 3.2, we need to replace x with 3.2 and then add. 4.5 + x = 4.5 + 3.2=7.7Solved Example on Evaluating an Algebraic ExpressionEvaluate the algebraic expression p + 3q + 2p - 3q, for p = 2 and q = - 5.Choices:A. 12B. 18C. 3D. 6Correct Answer: DSolution:Step 1: p + 3q + 2p - 3q [Original expression.]Step 2: = (p + 2p) + (3q - 3q) [Group the like terms together.]Step 3: = 3p [Solve within the grouping symbols.]Step 4: = 3 x 2 [Substitute 2 for p.]Step 5: = 6 [Multiply.]

How do you find the value of an algebraic expression by substituting a number for each variable and simplifying?

The answer to the question is given in the question!If you want to find the value of an algebraic expression, then you need to substitute numerical values for each of the variables in the expression, and then calculate and simplify the result.


How do you get the constant in algebraic expression?

By itself you cannot. You need to have a set of values for the variables and the expression which you need to solve.


How do you write an algebraic expression for the sum of a number and -6 is 4?

You cannot write an algebraic expression for that, you need an equation. The equation is n - 6 = 4


Why you need convert a expression into postfix expression?

You convert an (infix) expression into a postfix expression as part of the process of generating code to evaluate that expression.


What is value of an expression?

When you have an algebraic expression with variables in it, you need to know the the value of each variable. The value of the expression is found by replacing the variables with their values and simplifying. For example, evaluate 2xy-3x if x=5 and y=-1. 2xy-3x = 2*5*(-1) -3*5 = -10-15 = -25.
