Factorization Formulas — Class 8 CBSE

Factorize algebraic expressions using common factors, regrouping, and identities.

Key Formulas

Common Factor

ab + ac = a(b + c)

Regrouping

ax + bx + ay + by = x(a + b) + y(a + b) = (a + b)(x + y)

Using Identity 1

a^2 + 2ab + b^2 = (a + b)^2

Using Identity 2

a^2 - 2ab + b^2 = (a - b)^2

Using Identity 3

a^2 - b^2 = (a + b)(a - b)
