Answer 2

Answer:

x^2+y^2-z^2-8+5y-3z+3x

Step-by-step explanation:

Sum of the expressions : x^2+y^2+z^2

First expression: 4×2-5y+3z

Second expression:-3x+2z^2

Therefore Third Expression -> x^2 + y^2 + z^2 - { ( 4×2 - 5y + 3z) + ( -3x + 2z^2 ) }

-> x^2 + y^2 + z^2 { 8 - 5y + 3z - 3x + 2z^2}

->x^2 + y^2 + z^2 - 8 + 5y - 3z + 3x - 2z^2

-> x^2 + y^2 - z^2 - 8 + 5y - 3z + 3x (Ans.)
