expand f(x,y,z)2x^2+xy+y^2+100-z(x+y-100)

expand

f (x, y, z) 2 x^{2} + x y + y^{2} + 100 - z (x + y - 100)

f (x, y, z) \cdot 2 x^{2} + x y + y^{2} + 100 - x z - yz + 100 z

Solution steps

f (x, y, z) \cdot 2 x^{2} + x y + y^{2} + 100 - z (x + y - 100)

= 2 f x^{2} (,, x yz) + x y + y^{2} + 100 - z (x + y - 100)

Expand

- z (x + y - 100) : - x z - yz + 100 z

= f (x, y, z) \cdot 2 x^{2} + x y + y^{2} + 100 - x z - yz + 100 z
