Question

(4x-3y) ^3 expand the binomial. help :D

Answer 1

Use binomial expansion!

Answer 2

4x^3-3y^0 + 4x^2-3y^1+4x^1-3y2?

Answer 3

You have several choices here. You could memorize the first few binomial expansions:

(a+b)=a+b
(a+b)^2 = a^2 + 2ab + b^2
(a+b)^3= a^3 + 3a^2b +3ab^2 + b^3

or you could multiply out (a+b)(a+b)(a+b),

or you could look up and apply Pascal's Triangle.

Take your pick.

Answer 4

Please note: 4x^3 is not the same as the required (4x)^3.
