x^(2)-y^(2)-4xz+4z^(2)quad " fractorize "

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

If x^(2) + 3y^(2) + 4z^(2)+ 19 = 4 sqrt(3) ( x + y + z) , then the value of ( x - y + 4z) is:

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

Factorise 4x^(2) + y^(2) + z^(2) - 4xy - 2yz + 4xz .

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