Question

\[\left( s-3v \right)^{5}\] Expand using pascales triangle :)

Answer 1

oh! I got it: s^5 - 15s^4v + 90s^3v^2 - 270s^2v^3 + 405sv^4 - 243v^5

Answer 2

a = s
b = -3v

s^5 + 5s^4(-3v) + 10s^3(-3v)^2 + 10s^2(-3v)^3 + 5s(-3v)^4 + (-3v)^5

s^5 - 15s^4v + 90s^3v^2 - 270s^2v^3 + 405sv^4 - 243v^5
