Question

Use the binomial theorem to expand (2x-3y)^4. Show all your work.

Answer 1

So the Binomial theorem works off Pascal's triangle. I'll get to explaining it in a minute do you have a calculator with you?

Answer 2

(2x - 3y)^4
= 4C0(2x)^(4-0)(-3y)^0 + 4C1(2x)^(4-1)(-3y)^1 + 4C2(2x)^(4-2)(-3y)^2 + 4C3(2x)^(4-3)(-3y)^3 + 4C4(2x)^(4-4)(-3y)^4

just simplify that, get ur answer

Answer 3

Sorry guys, I figured it out before you could answer. xD
