Simplifying Expressions

Simplifying expressions involves combining like terms and reducing expressions to their simplest form.

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

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

4x^2 - 5x + 11

5a + 9

6x - 3

50.12a

4.4v

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

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