# Factorise the following expressions

36a^{2}b – 60 a^{2}bc

Answer :

In the given expression

Check the common factors for all terms;

⇒ [2 × 2 × 3 × 3 × a × a × b - 2 × 2 × 3 × 5 × a × a × b × c]

⇒ 2 × 2 × 3 × a × a × b[3 × b-5 × c]

⇒ 12a^{2}b[3b-5c]

∴ 36a^{2}b - 60 a^{2}bc = 12a^{2}b[3b-5c]
