Ex 14.2, 3 (Method 1) Factorise the expressions. (i) a๐‘ฅ^2 + b๐‘ฅ a๐‘ฅ^2 = a ร— ๐‘ฅ ร— ๐‘ฅ b๐‘ฅ = b ร— ๐‘ฅ So, ๐‘ฅ is a common factor. a๐‘ฅ^2 + b๐‘ฅ = (a ร— ๐‘ฅ ร— ๐‘ฅ) + (b ร— ๐‘ฅ) Taking ๐‘ฅ common, = ๐‘ฅ ((a ร— ๐‘ฅ) + b) = ๐’™ (a๐’™ + b) Ex 14.2, 3 (Method 2) Factorise the expressions. (i) a๐‘ฅ^2 + b๐‘ฅ a๐‘ฅ^2 + b๐‘ฅ = (a ร— ๐‘ฅ ร— ๐‘ฅ) + (b ร— ๐‘ฅ) Taking ๐‘ฅ common, = ๐’™ (a๐’™ + b)
