" One of the factors of "x^(2)+y^(2)+2xy-z^(2)" is "

One of the factors of 4x^(2) + y^(2) + 14x-7y-4xy+12 is equal to

Factors of -5x^2 y^2 z are

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

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

Factorise : (v) x^(2) - 2xy + y^(2) - z^(2)

factorize : x^2+y^2-z^2-2xy

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))
