How do you expand #(x^4-y^3)^3#? Precalculus The Binomial Theorem Pascal's Triangle and Binomial Expansion 1 Answer Gerardina C. Jul 6, 2016 #x^12-3x^8y^3+3x^4y^6-y^9# Explanation: Since #(a+b)^3=a^3+3a^2b+3ab^2+b^3# you have: #(x^4-y^3)^3=(x^4)^3+3(x^4)^2(-y^3)+3(x^4)(-y^3)^2+(-y^3)^3# that's #x^12-3x^8y^3+3x^4y^6-y^9# Answer link Related questions What is Pascal's triangle?
