00:00 Introduction: Polynomial Algebraic Identities
01:31 Identity I: (x + y)^2 = x^2 + 2xy + y^2
23:43 Identity II: (x – y)^2 = x^2 – 2xy + y^2
32:34 Identity III: x^2 – y^2 = (x + y) (x – y)
39:27 Identity IV: (x + a) (x + b) = x2 + (a + b)x + ab
43:19 Identity V: (x + y + z)^2 = x^2 + y^2 + z^2 + 2xy + 2yz + 2zx
49:20 Identity VI: (x + y)^3 = x^3 + y^3 + 3xy (x + y)
