Ex 14.1, 2 (Method 1) Factorise the following expressions. (ix) ๐ฅ^2 y z + x ๐ฆ^2z + x y ๐ง^2 ๐ฅ^2 y z = ๐ฅ^2 ร y ร z = ๐ฅ ร ๐ฅ ร y ร z ๐ฅ๐ฆ^2z = ๐ฅ ร ๐ฆ^2 ร z = ๐ฅ ร y ร y ร z ๐ฅy๐ง^2 = ๐ฅ ร y ร ๐ง^2 = ๐ฅ ร y ร z ร z So, x, y and z are the common factors. ๐ฅ^2 y z + ๐ฅ๐ฆ^2z + ๐ฅy๐ง^2 = (๐ฅ ร ๐ฅ ร y ร z) + (๐ฅ ร y ร y ร z) + (๐ฅ ร y ร z ร z) Taking ๐ฅ ร y ร z common, = ๐ฅ ร y ร z ร (๐ฅ + y + z) = ๐yz (๐ + y + z) Ex 14.1, 2 (Method 2) Factorise the following expressions. (ix) ๐ฅ^2 y z + x ๐ฆ^2z + x y ๐ง^2 ๐ฅ^2 y z + x ๐ฆ^2z + x y ๐ง^2 = (๐ฅ ร ๐ฅyz) + (y ร ๐ฅyz) + (z ร ๐ฅyz) Taking ๐ฅyz common, = ๐yz (๐ + y + z)
