x^(2)+y^(2)-z^(2)-2xy

The equation 12x^(2)-2y^(2)-6z^(2)-2xy-8xy+6xz=0 represents

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+2z)(x^(2)+y^(2)+4z^(2)-xy-2yz-2zx)

Simplify: (x+y+2z)(x^(2)+y^(2)+4z^(2)-xy-2yz-2zx)

Factorize: 2xy-(x^(2)+y^(2)-z^(2))

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

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

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