solve this simplify
please solve it's urgent

the answer come X square + 2 y square + 2 z square -x- y -z
solve this simplify step by step

please don't give unnecessary answer​

Answer 1

Answer:

2x²-y-[z-(2y² -x) – {2z² – (y-x²) }]

→ 2x²-y-[z - 2y² + x– {2z² – y + x² }]

→ 2x²-y-[z - 2y² + x– 2z² + y - x² ]

→ 2x²-y- z + 2y² - x + 2z² - y + x²

→ 2x² + x² -x -y-y +2y² -z +2z²

→ 3x² - x - 2y +2y² - z+2z²

Answer 2

Answer:

Heat is the form of energy that is transferred between systems or objects with different temperatures (flowing from the high-temperature system to the low-temperature system). Also referred to as heat energy or thermal energy. Heat is typically measured in Btu, calories or joules
