Answer:
The correct option is B.
Step-by-step explanation:
The given expression is
[tex](2x-y)^3[/tex]
Binomial expansion of given expression is
[tex](2x)^3-3(2x)^2(y)+3(2x)(y)^2-(y)^3[/tex] [tex][\because (a-b)^3=a^3-3a^2b+3ab^2-b^3][/tex]
[tex]8x^3-3(4x^2)y+6xy^2-y^3[/tex]
[tex]8x^3-12x^2y+6xy^2-y^3[/tex]
The binomial expansion of given expression is [tex]8x^3-12x^2y+6xy^2-y^3[/tex]
Therefore the correct option is B.
