(x)(x+2y+4z)^(2)

Factorize each of the following expressions: (2x+1)^(2)-9x^(4)(2)x^(4)-(2y-3z)^(2)a^(2)-b^(2)+a-b(4)16a^(4)-b^(4)a^(4)-16(b-c)^(4)

Factorize: (3x-2y)^(3)+(2y-4z)^(3)+(4z-3x)^(3)

If (x+ y-z -1)^(2) + (z+ x-y - 2)^(2) + (z+y-x-4)^(2)=0 find x+ y+z =?

Prove: |(z, x, y),( z^2,x^2,y^2),(z^4,x^4,y^4)|=|(x, y, z),( x^2,y^2,z^2),(x^4,y^4,z^4)|=|(x^2,y^2,z^2),(x^4,y^4,z^4),(x, y, z)|=x y z(x-y)(y-z)(z-x)(x+y+z) .

Prove that 4x^2(y-z)+y^2(2x-z)+z^2(2x+y)-4xyz = (2x+y)(y-z)(2x-z)

Find the product: (x+y+2z)(x^2+y^2+4z^2-x y-2y z-2z x)

If x^(2)+y^(2)+z^(2)=2(x-y-z)-3 Find the value of 2x-3y+4z

If x/2=y/3=z/7 then (2x-5y+4z)/(2y)=

radius of circle x^(2)+y^(2)+z^(2)-2y-4z-20=0,x+2y+2z=15
