Best Answer

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.)


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..

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

Can you add or subtract two pointer variables?

Only subtract, if they are pointers to the same type. Example:double coefficients [12], *p= &coefficients[3], *q= &coefficients[4];printf ("q-p=%d\n", (int)(q-p));Note: The result is 1, not sizeof (double)

What are the steps and rules for adding and subtracting monomials?

A monomial is a polynomial that has just one term. So to add or subtract monomials, is the same as we add or subtract like terms (terms that have exactly the same variable part). Since we are dealing with monomials, the restriction is that the exponent(s) of the variable(s) must be positive integer(s). Examples of monomials: 10xy, -5xy2, -3x2, 3w3z6, -7xy, -4x2, 2xy2, 9w3z6. So, how to add or subtract them? First detect where the like terms (monomials) are, then group them (write them next to each other), then combine (ad or subtract their coefficients, and write next to the result the common variable part). 10xy -7xy = 3xy (subtract since the coefficients have different sign). -5xy2 +2xy2 = -3xy2 (subtract since the coefficients have different sign). -3x2 -4x2 = -7x2 (add because the coefficients have the same sign). 3w3z6 + 9w3z6 = 12w3z6 (add because the coefficients have the same sign).

How do you use variable in an addition or subtraction?

well, if you want to add apples to bananas you can't do that it's the same with variables, the coefficients can be different but to add and subtract the variables have to be the same for ex: you can't do 4x+3y because they have different variables you can do 4x+3x because they have the same variables all you do is add the coefficients and keep the variable so you would get 7x
