You can put this solution on YOUR website! (2x+3)^6
----
= 6C6*(2x)^6 + 6C5*(2x)^5*3 + 6C4*(2x)^4*3^2 + 6C3*(2x)^3*3^3 + 6C2*(2x)^2*3^4
+ 6C1*(2x)^1*3^5 + 6C0*3^6
-------------------------------
= 64x^6 + 6*32x^5*3 + 15*16x^4*9 + 20*8x^3*27 + 15*4x^2*81 + 6*2x*243 + 729
-------------------------------
= 64x*6 + 576x^5 + 2160x^4 + 4320x^3 + 4860x^2 + 2916x + 729
