Example 1 Factorise 12๐‘Ž^2b + 15ใ€–๐‘Ž๐‘ใ€—^2 12a^2b + 15ab^2 12a^2b = 12 ร— a^2b = 2 ร— 2 ร— 3 ร— a^2b = 2 ร— 2 ร— 3 ร— a ร— a ร— b 15ab^2 = 15 ร— ab^2 = 3 ร— 5 ร— ab^2 = 3 ร— 5 ร— a ร— b ร— b Now, 12ab^2 = 2 ร— 2 ร— 3 ร— a ร— a ร— b 15ab^2 = 3 ร— 5 ร— a ร— b ร— b So, 3, a, b are common factors. 12ab^2 + 15ab^2 = 2 ร— 2 ร— 3 ร— a ร— a ร— b + 3 ร— 5 ร— a ร— b ร— b = 3 ร— a ร— b (2 ร— 2 ร— a + 5 ร— b) = 3ab (4a + 5b)
