### Factorisation Class 8 Notes Conceptual Facts

- Prime factors of 30 (say) = 2 x 3 x 5
- Factors of algebraic expression 4xy = 4 x x x y
- 1 is a factor of every expression.
- Method of common factors
- 4x + 24 = 4(x + 6)
- Method of factorisation by regrouping terms

6xy + 3y = 2 x 3 x x x y + xy = 3 xy (2x + 1) = 3y (2x + 1)

Factorisation using identities

a^{2} + 2ab + b^{2}– (a + b)^{2
}a^{2} – 2ab + b^{2}= (a-b)^{2
}a^{2} – b^{2} = (a + b) (a – b)
