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

Factorize: 4x^(2)-4xy+y^(2)-9z^(2) (ii) 16-x^(2)-2xy-y^(2)x^(4)-(x-z)^(4)

Factorization by taking out the common factors: x(x^(2)+y^(2)-z^(2))+y(-x^(2)-y^(2)+z^(2))-z(x^(2)+y^(2)-z^(2))

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

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

Factorize x^(2)+y^(2)+x+y+2xy

Factorize 6x^2y+2xy
