Answer 1

Answer:

$((x \div 7) - (y \div 8))(7 {x}^{2} - 8 {y}^{2} ) \\ (x \div 7) \times (7 {x}^{2} - 8 {y}^{2} ) - (y \div 8) \times (7 {x}^{2} - 8 {y}^{2} ) \\ (x \times 7 {x}^{2} \div 7) - (x \times 8 {y}^{2} \div 7) - (y \times 7 {x}^{2} \div 8) + (y \times 8 {y}^{2} ) \div 8 \\ {x}^{3 } - (8x {y}^{2} \div 7) -( 7 {x}^{2} y \div 8) + {y}^{3}$
