Ex 14.1, 2 (Method 1) Factorise the following expressions. (iii) 7๐‘Ž^2 + 14a 7๐‘Ž^2 + 14a 7๐‘Ž^2 = 7 ร— ๐‘Ž^2 = 7 ร— a ร— a 14a = 14 ร— a = 7 ร— a ร— a So, 7 and a are the common factors. 7๐‘Ž^2 + 14a = (7 ร— a ร— a) + (2 ร— 7 ร— a) = (7 ร— a) (a + 2) = 7a (a + 2) Ex 14.1, 2 (Method 2) Factorise the following expressions. (iii) 7๐‘Ž^2 + 14a 7๐‘Ž^2 + 14a = 7๐‘Ž^2 + (7 ร— 2) a = (7a ร— a) + (7a ร— 2) Taking 7a common, = 7a (a + 2)
