Ex 12.3, 2 (Method 1) Separating each term Divide the given polynomial by the given monomial. (i) (5๐ฅ^2 โ 6x) รท 3x ใ5๐ฅใ^2โ6๐ฅ Taking x common, = x (5x โ 6) Dividing (5๐ฅ^2 โ 6๐ฅ)/3๐ฅ = (๐ฅ (5๐ฅ โ 6))/3๐ฅ = ๐ฅ/๐ฅ ร (5๐ฅ โ 6)/3 = (๐๐ โ ๐)/๐ Ex 12.3, 2 (Method 2) Cancelling terms Divide the given polynomial by the given monomial. (i) (5๐ฅ^2 โ 6x) รท 3x(5๐ฅ^2 โ 6๐ฅ)/3๐ฅ = (๐๐^๐)/๐๐ โ ๐๐/๐๐ = (5/3ร ๐ฅ^2/๐ฅ) โ (6/3ร๐ฅ/๐ฅ) = (5/3 " ร " ๐ฅ)โ 2 = 5/3 ๐ฅ โ 2 = (5๐ฅ โ 2 ร 3)/3 = (๐๐ โ ๐)/๐
