(-2x+3y+2z)^(2)

If (2x-y)^(2)+(3y-z)^(2)=0 then x:y:z is

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

Add : x y ^(2) z ^(2)+ 3x ^(2) y ^(2) z - 4x ^(2)yz ^(2), - 9x ^(2) y ^(2) z + 3x y ^(2) z ^(2) + x ^(2) yz ^(2)

The system of linear equations x+y+z =2, 2x+3y+2z = 5 2x +3y+ (a^(2)-1)z = a + 1

Write the following in expanded form: (i) (9x+2y+z)^(2)( ii) (3x+2y-z)^(2)( iii) (x-2y-3z)^(2)( iv) (-x+2y+z)^(2)

The transformed equation of 2x^(2)-3y^(2)+z^(2)+4x+6y-4z-2=0 when the axes are translated to the point (-1, 1, 2) is

If x+y+z=1, then 1-3x^(2)-3y^(2)-3z^(2)+2x^(3)+2y^(3)+2z^(3) is equal to
