(2-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)

Find the product. (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)

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)+y^(2)+z^(2)-4xy-3yz+4xz

Multiply x^(2)+4y^(2)+z^(2)+2xy+xz-2yz by (-z+x-2y)

Multiply: x^(2)+4y^(2)+z^(2)+2xy+xz-2yz by x-2y-z
