4b - 9 + 2b + 8

Coefficients are the numbers in front of the variables.

Therefore the coefficient of 4b is 4 and the coefficient of 2b is 2.

The like terms are 2b and 2b, but also -9 and 8.

Constant terms are the ones that do not contain a variable. -9 and 8 are the constants.

4b - 9 + 2b + 8 can be simplified (by combining like terms) to give 2b - 1

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

Is combining like terms much harder to do when the coefficients and constant terms are not integers?

The answer depends on how fluently you can work with fractions.

How do you add like terms?

To add like terms, find the terms that have the same (or no) variable, and combine the coefficients of the terms. For instance, if you have a+b where a and b are real numbers, you can combine them.

What are the rules in addition of polynomials?

Add together the coefficients of "like" terms. Like terms are those that have the same powers of the variables in the polynomials.

What is the definition for like terms?

like terms - are terms that have identical variable parts and constant terms

What is a Characteristic for like terms?

They have the same form for any variables, but the numerical coefficients can be different.

How do you solve multiplication with like terms?

Just multiply the coefficients, leave the variable the same, and add the exponents.

What are liked terms?

Like terms are terms that contain the same variables raised to the same power. Here is an example: 123xyz and 575676xyz. Like terms can be combined by adding the numerical coefficients, for example , 5x+6x+15x=26x

Are temperature coefficients alwaws constant?

A: As an engineer it surely like to drink to that. No the coefficient varies from component to component and even with the environment to boot.

How do you identify like terms?

To identify like terms you look at the variables in the terms for example; 4X,3d,2X2,32d the only like terms in there are 32d and 3d because the variable has to be to the same power Thanks for making me feel like a teacher hee hee ur welcome :]

When can you add or subtract coefficients?

You can add and subtract coefficients when they occur in like terms, which means they have the same variable. 2x + 3x = 5x (This addition can take place because all of the variables are x, and are therefore like terms.) and 5y - 2y = 3y (This subtraction can take place because all of the variables are y, and are therefore like terms.) However, if the variables differ, they are unlike terms, and you cannot add or subtract the coefficients. For example: 2a + 3b cannot be added because a and b are different variables, and therefore unlike terms. 3c - 2d cannot occur because c and d are different variables, and therefore unlike terms..

The steps in collecting like terms?

1) Identify characteristics not all terms have 2) Separate into characteristics 3) Gather like terms
