Ex 12.1, 2 (Method 1) Factorise the following expressions. (ix) đĽ^2 y z + x đŚ^2z + x y đ§^2đĽ^2 y z + x đŚ^2z + x y đ§^2 = (đĽ Ă đyz) + (y Ă đyz) + (z Ă đyz) Taking đyz common, = đyz (đ + y + z) Ex 12.1, 2 (Method 2) Factorise the following expressions. (ix) đĽ^2 y z + x đŚ^2z + x y đ§^2 đĽ^2 y z ăđĽđŚă^2z đĽyđ§^2 So, x, y and z are the common factors. đĽ^2 y z + đĽđŚ^2z + đĽyđ§^2 = (đĽ Ă đĽ Ă y Ă z) + (đĽ Ă y Ă y Ă z) + (đĽ Ă y Ă z Ă z) Taking đ Ă y Ă z common, = đĽ Ă y Ă z Ă (đĽ + y + z) = đyz (đ + y + z) = đĽ^2 Ă y Ă z = đĽ Ă đŚ^2 Ă z = đĽ Ă y Ă đ§^2 = đ Ă đ Ă y Ă z = đ Ă y Ă y Ă z = đ Ă y Ă z Ă z
