You can put this solution on YOUR website! The coefficients of a binomial expansion such as this can be found using Pascal's Triangle:
1
11
121
1331
14641
Here is the group for n=4 power...
Now when you expand a binomial, the powers of the first term go from four to zero, and the powers of the second term go from zero to four...so that =
So the coefficient of the x^2 term is 24.
