" 20."x^(2)-y^(2)-4xz+4z^(2)

Factorize: x^(2)-y^(2)-4xz+4z^(2)

Factorize each of the following algebraic expressions: a^(2)+2ab+b^(2)-c^(2)(2)49-x^(2)-y^(2)+2xya^(2)+4b^(2)-4ab-4c^(2)(4)x^(2)-y^(2)-4xz+4z^(2)

Factorise : 3x^(2)+4xy+y^(2)-2xz-z^(2)

Factories the following : 25x^(2) + 4y^(2) + 9z^(2) - 20 xy + 12yz + 30 xz

Factorise : 2x^(2) + y^(2) + 8z^(2) - 2sqrt(2)xy + 4sqrt(2)yz - 8xz
