निम्नलिखित प्रत्येक व्यंजको को सरल कीजिए :
` ( x+ y+z)^(2) +(x+ y/2+z/3)^(2) - (x/2 + y/3 +z/4)^(2)`

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

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

3x - [4y - {7x - (3z - 2y) + 4z - 3(x + 3y - 2z)}]

2x + 3y + z = 11, x + 2y + z = 8, x-y + z = 2

2x + 3y + 3z = 5, x-2y + z = -4,3x-y-2z = 3

The value of the expression ((x ^(2) - y ^(2)) ^(3) + ( y ^(2) - z ^(2)) ^(3) + (z ^(2) - x ^(2)) ^(3))/((x - y) ^(3) + ( y - z) ^(3) + (z - x ) ^(3)) is

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