Use the Binomial Theorem to expand and simplify the expression.

You need first to factorize , such that:

 

You need to use the binomial formula, such that:

You need to replace 4x for x, 1 for y and 3 for n, such that:

By definition, nC0 = nCn = 1, hence

You need to replace 4x for x, 1 for y and 3 for n, such that:

By definition, nC0 = nCn = 1, hence

By definition nC1 = nC(n-1) = n, hence

Replacing the binomial expansion  for   yields:

Grouping the like terms yields:

Hence, expanding and simplifying the expression yields
