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