Question

Please Answer??? The binomial expansion of (2x-y)^3 is

Answer 1

Answer:

The correct option is B.

Step-by-step explanation:

The given expression is

$(2x-y)^3$

Binomial expansion of given expression is

$(2x)^3-3(2x)^2(y)+3(2x)(y)^2-(y)^3$      $[\because (a-b)^3=a^3-3a^2b+3ab^2-b^3]$

$8x^3-3(4x^2)y+6xy^2-y^3$

$8x^3-12x^2y+6xy^2-y^3$

The binomial expansion of given expression is $8x^3-12x^2y+6xy^2-y^3$

Therefore the correct option is B.
