Combine like terms

Front

What does it mean to combine like terms in an expression?

Back

Combining like terms means to simplify an expression by adding or subtracting terms that have the same variable raised to the same power.

Front

What are like terms?

Back

Like terms are terms in an expression that have the same variable and exponent. For example, 3x and 5x are like terms, while 3x and 4y are not.

How do you combine the terms 8r and -2r?

Back

You subtract the coefficients: 8r - 2r = (8 - 2)r = 6r.

Front

What is the result of combining -5c and -6c?

Back

The result is -11c, as you add the coefficients: -5 + (-6) = -11.

Front

How do you simplify the expression 11q + 8 - q?

Back

You combine like terms: (11q - q) + 8 = 10q + 8.

Front

What is the simplified form of 7m - 10 - 4m + 3?

Back

Combine like terms: (7m - 4m) + (-10 + 3) = 3m - 7.

Front

What happens when you combine -8d and 8d?

Back

The result is 0, as they cancel each other out: -8d + 8d = 0.

Front

What is the first step in combining like terms?

Back

Identify and group the like terms in the expression.

Front

Can constants be combined with variable terms?

Back

No, constants can only be combined with other constants, and variable terms can only be combined with like variable terms.

Front

What is the importance of combining like terms in algebra?

Back

Combining like terms simplifies expressions, making them easier to work with and solve.
