Use pascal's triangle to expand the binomial<br> (d-5y)^6<br><br> please show work
Ratling [72]
Pascals triangle to the 6th:
1                                     x^0
1 1                                  x^1
1 2 1                               x^2
1 3 3 1                           x^3
1 4 6 4 1                        x^4
1 5 10 10 5 1                x^5
1 6 15 20 15 6 1          x^6<span>

</span>the problem is to the 6th power so your going to use the 6th row of pascals triangle (don't count the first row). these numbers represent the coefficients of the variables

1(d-5y)^6 + 6(d-5y)^5 + 15(d-5y)^4 + 20(d-5y)^3 + 15(d-5y)^2 + 6(d-5y) + 1
then simplify
