Answer 1

Answer:

Option 'B' is your required answer

Step-by-step explanation:

(x-y)^3

= (x-y)^2 × (x-y)

(Applying (a-b)^2 formula...)

= {(x)^2+(y)^2 - 2.x.y} (x-y)

= x{( x)^2 +(y)^2 - 2.x.y} - y{(x)^2+(y)^2-2.x.y}

= x^3 +x.y^2 - 2x^2y - y.x^2 - y^3 +2xy^2

= x^3+3xy^2-3x^2y-y^3

=x^3-3x^2y+3xy^2-y^3

Hope it will help you ♥️
