Combining Like Terms

Front

What are like terms?

Back

Like terms are terms that have the same variable raised to the same power. For example, 3x and -9x are like terms because they both contain the variable x.

Front

Combine the like terms: 3x + 7 - 9x + 24y + 2x²

Back

-3x + 7 + 24y + 2x² (like terms: 3x and -9x combine to -6x)

Front

What is the result of combining -4x and -10x?

Back

-14x (combine the coefficients: -4 + -10 = -14)

Front

Combine the like terms: 2r + 2 + 5r - 2 + r

Back

8r (combine 2r, 5r, and r to get 8r)

Front

Combine the like terms: 6x + 1 + 7x

Back

13x + 1 (combine 6x and 7x to get 13x)

Front

What is the coefficient in the term 5x?

Back

5 (the coefficient is the number in front of the variable)

Front

What is the constant in the expression 3x + 4?

Back

4 (the constant is the term without a variable)

Front

Combine the like terms: 4a + 3b + 2a - b

Back

6a + 2b (combine 4a and 2a to get 6a, and 3b and -b to get 2b)

Front

What is the first step in combining like terms?

Back

Identify and group the like terms together.

Front

Combine the like terms: 10y - 3y + 5y

Back

12y (combine 10y, -3y, and 5y to get 12y)
