1. Multiplying a Polynomial by a Polynomial

In multiplication of polynomials with polynomials, we should always look for like terms, if any, and combine them.

• Multiplying a binomial by a binomial - In this case, the distributive law of multiplication is applied. Each term of one binomial is multiplied by each term of another. After the polynomial is multiplied, it is necessary to search for similar terms and to combine them.

• Multiplying a binomial by a trinomial - In this case, we also need to add each binomial term to each trinomial term.

Tips for Solving Exercise 8.4 Class 8 Chapter 8 Algebraic Expressions and Identities

Students must go through the tips provided by subject experts of eSaral to solve ex 8.4 questions for class 8 maths chapter 8 algebraic expressions and identities.
