Question

what term can be combined in adding or subtracting polynomials?​

Answer 1

Like terms can be combined in adding or subtracting polynomials.

• This can be explained in the following way:

• Addition and subtraction of polynomials depend on three main things which include:

1. Coefficient of the polynomial expression
2. Variable of the polynomial expression
3. An exponent of the polynomial expression

• Like terms is that expression in polynomials which have:

1. Same or different coefficient
2. Same variable
3. Same exponent

• For example, 2x² + 5x² + 3y is a polynomial expression in which 2x² and 5x² are like terms that can be added while 3y is unlike term and is written as it is in the solution.

• Hence, like terms or similar terms can only be combined for adding and subtracting polynomial expression.
