What are like terms?

Back

Like terms are terms that have the same variable raised to the same power. For example, 4x and -3x are like terms.

How do you combine like terms?

Back

To combine like terms, add or subtract their coefficients while keeping the variable part the same. For example, 4x - 3x = 1x or simply x.

Simplify: 4x^2 - 3x + 11 - 2x

Back

4x^2 - 5x + 11

Front

What is the coefficient in the expression 7x + 3?

Back

The coefficient is 7, which is the number multiplying the variable x.

What does it mean to reduce an expression?

Back

Reducing an expression means simplifying it to its lowest terms, often by combining like terms or eliminating unnecessary parts.
