" 2."(x-y-z)(x^(2)+y^(2)+z^(2)+xy-yz+xz)

Multiply by using the correct identity (x+y-z)(x^(2)+y^(2)+z^(2)-xy+xz+yz)

Find the product. (x-y-z)(x^2+y^2+z^2+xy-yz+xz)

Find the following produts: (i) (x+y+2z)(x^(2)+y^(2)+4z^(2)-xy-2yz-2xz)(2x-y+2z)(4x^(2)+y^(2)+9z^(2)+2xy+3yz-6xz)

Evaluate : (2x-y+3z)(4x^(2)+y^(2)+9z^(2)+2xy+3yz-6xz)

Factorise 4x^(2) + y^(2) + z^(2) - 4xy - 2yz + 4xz .

Simplify : (x- 2y + 3z ) ( x^(2) + 4y^(2) + 9z^(2) + 2xy + 6yz - 3xz)

Factorise : - 4x^(2) +9y^(2)+16z^(2)+12xy-24yz-16xz

Factorise : 4x^(2) + 9y^(2) + 16z^(2) +12xy - 24yz - 16xz
