Plzz Help !!!! What í the equation of (2x+y)^3 ???
Murljashka [212]
If you are talking about the binomial being expanded then it would be:

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

The y in the second term is not part of the exponent

And since you are raising the binomial to the third, you would be using the third row of Pascal's triangle.

Hope this helped!
