Multiplication of Algebraic Expressions: Introduction

While multiplying we need to take care of some points about the multiplication of like and unlike terms.

1. Multiplication of Like Terms

  • The coefficients will get multiplied.
  • The power will not get multiplied but the resultant variable will be the addition of the individual powers.

Example

  • The product of 4x and 3x will be 12x2.
  • The product of 5x, 3x and 4x will be 60x3.

2. Multiplication of Unlike Terms

  • The coefficients will get multiplied.
  • The power will remain the same if the variable is different.
  • If some of the variables are the same then their powers will be added.

Example

  • The product of 2p and 3q will be 6pq
  • The product of 2x2y, 3x and 9 will┬ábe 54x3y
