Question

Use Pascal’s Triangle to expand the binomial.

( 2x + y)^6

Answer 1

you must be knowing pascal triangle,dont you ?

Answer 2

yes I do know the basic triangle, but I just don't know what I do when it is "2x" and not just "x"

Answer 3

I know the (x+y)^1 power type triangle

Answer 4

let 2x= X
now you should be able to expand (X+y)^6 using pascal triangle.
lastly, substitute, X for 2x ..
this should help..

Answer 5

Oh I think I got it. is this right? (2x)^6+6(2x)^5(y)+15(2x)^4(y)^2+20(2x)^3(y)^3+15(2x)^2(y)^4+6(2x)(y)^5+(y)^6?
