How do you combine like terms?

Back

To combine like terms, add or subtract the coefficients of the terms that have the same variable. For example, 3x + 5x = (3 + 5)x = 8x.

The result is 8r.

Front

What is the result of combining y + y + x + x?

Back

The result is 2x + 2y.

What is the result of combining 5z - 4z?

Back

The result is 1z.

Front

What does the term 'coefficient' mean?

Back

A coefficient is a numerical factor in a term. For example, in 4x, 4 is the coefficient.

Front

What is the difference between like terms and unlike terms?

Back

Like terms have the same variable and exponent, while unlike terms do not. For example, 2x and 3x are like terms, but 2x and 3y are unlike terms.

What is the result of combining 2x + 3x + 4y?

Back

The result is 5x + 4y.
