Answer 1

Answer:

x^3-8y^3-6x^2y+24xy^2

Answer 2

Answer:

${x}^{3 } - 6 {x}^{2} y + 12x{y}^{2} - 8 {y}^{3}$

Step-by-step explanation:

${(x - 2y)}^{3} \\ using \: \: identity \: \\ {(x - y)}^{3} = {x}^{3} - 3 {x}^{2} y + 3x {y}^{2} - {y}^{3}$

Now putting values of x=x and y=2y

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

${x}^{3 } - 6 {x}^{2} y + 12x{y}^{2} - 8 {y}^{3}$
