I'm in honor's Algebra 2 and before christmahaunakwanzica break, I was assigned a project that I know forget how to do. We have to expand a binomial using Pascal's Triangle. My problem is (5x-3y)^9. So far I got

1(5x)^9 + 9(5x)^8(-3y)^1 + 36(5x)^7(-3y)^2 + 84(5x)^6(-3y)^3 + 126(5x)^5(-3y)^4 + 126(5x)^4(-3y)^5 + 84(5x)^3(-3y)^6 + 36(5x)^2(-3y)^7 + 9(5x)^1(-3y)^8 + (-3y)^9 .

Now the problem is I don't know what to do know to simplify it more. I'm senile now when it comes to math because I haven't been to school for so long. I hope someone can help cause this is due tomorrow...
