Introducing Algebraic Expressions Multiplying Algebraic Expressions Dividing Algebraic Expressions

Quick Facts

Lesson: 22: Algebraic Expressions
Topic: Multiplying Algebraic Expressions
Domain: Algebra

Multiplying does not need like terms. Two rules do all the work: the coefficients multiply and the powers add, so 2x² × 5x³ is 10x⁵.

Study Tip

Everything outside a bracket multiplies everything inside it. Picture 3(x + 4) as a rectangle 3 high and x + 4 long, which splits into 3x and 12.
