Overview

Special products, factorization, HCF and LCM of polynomials, and rational expressions form a connected part of algebra. Special products help in quick expansion and mental calculation. Factorization is the reverse process, where a polynomial is written as a product of simpler polynomials. HCF and LC

Key Concepts

The identities are (a + b)^2

The identities are (a + b)^2 = a^2 + 2ab + b^2 and (a - b)^2 = a^2 - 2ab + b^2. The only difference is the sign of the middle term 2ab.

The identity (a + b)(a

The identity (a + b)(a - b) = a^2 - b^2 gives a quick way to multiply numbers and factorise expressions.

The identities (x + a)(x +

The identities (x + a)(x + b) = x^2 + (a + b)x + ab and (ax + b)(cx + d) = acx^2 + (ad + bc)x + bd help expand binomials and trinomials.

The cube of sum is (a

The cube of sum is (a + b)^3 = a^3 + 3ab(a + b) + b^3, and the cube of difference is (a - b)^3 = a^3 - 3ab(a - b) - b^3.

The factorization formulas are (a +

The factorization formulas are (a + b)(a^2 - ab + b^2) = a^3 + b^3 and (a - b)(a^2 + ab + b^2) = a^3 - b^3.

Learning Objectives

  • Use standard identities for squares, cubes, and products of algebraic expressions.
  • Expand expressions quickly using special products such as square of sum, square of difference, difference of squares, and cube identities.
  • Factorise polynomials using common factors, identities, sum and difference of cubes, and splitting the middle term.
  • Find the HCF and LCM of monomials and polynomials by factorization.
  • Identify rational expressions and distinguish them from polynomials.
