$Factorisation using identities | Algebraic expression & Identities| OD Grade 9 | Math | Khan Academy In this video, you will learn how to master the factorization of the advanced algebraic identity $a^4 + a^2b^2 + b^4$. We start with a clear, step-by-step breakdown of how this specific quartic expression is broken down into its quadratic factors, $(a^2 + ab + b^2)(a^2 - ab + b^2)$. This video walks through multiple solved examples of problems on factorization using different algebraic identities. Courses on Khan Academy are always 100% free.
