Question

(x+y)^3-(x-y)^3-6Y(X^2-Y^2​

Answer 1

Step-by-step explanation:

${(x + y)}^{3} - {(x - y)}^{3} - 6y( {x}^{2} - {y}^{2} )$

${x}^{3} + {y}^{3} - {x}^{3} + {y}^{3} - 6y {x}^{2} + 6 {y}^{3}$

${x}^{3} - {x}^{3} + {y}^{3} + {y}^{3} + {6y}^{3} - {6yx}^{2}$

$0 + {8y}^{3} - {6yx}^{2}$

${8y}^{3} - {6yx}^{2}$
