This is the n=4 row and represent the coefficients...
For (1 + x)^4, the powers of x increase from zero to four, term by term...so that
(1 + x)^4 = 1 + 4x + 6x^2 + 4x^3 + x^4
You can put this solution on YOUR website! Look at Pascal's triangle and choose the 5th row, one more than the degree.

So arrange your polynomial with descending powers of x starting with exponent 4 using the coefficients above.
