x + y)2 = x2 + 2xy + y2 (x - y)2 = x2 - 2xy + y2 Example 1: If x = 10, y = 5a (10 + 5a)2 = 102 + 2·10·5a + (5a)2 = 100 + 100a + 25a2 Example 2: if x = 10 and y is 4 (10 - 4)2 = 102 - 2·10·4 + 42 = 100 - 80 + 16 = 36 The opposite is also true: 25 + 20a + 4a2 = 52 + 2·2·5 + (2a)2 = (5 + 2a)2 Consequences of the above formulas: (-x + y)2 = (y - x)2 = y2 - 2xy + x2 (-x - y)2 = (-(x + y))2 = (x + y)2 = x2 + 2xy + y2 Formulas for 3rd degree: (x + y)3 = x3 + 3x2y + 3xy2 + y3 (x - y)3 = x3 - 3x2y + 3xy2 - y3 Example: (1 + a2)3 = 13 + 3.12.a2 + 3.1.(a2)2 + (a2)3 = 1 + 3a2 + 3a4 + a6 (x + y + z)2 = x2 + y2 + z2 + 2xy + 2xz + 2yz (x - y - z)2 = x2 + y2 + z2 - 2xy - 2xz + 2yz Factor Rules x2 - y2 = (x - y)(x + y) x2 + y2 = (x + y)2 - 2xy or x2 + y2 = (x - y)2 + 2xy Example: 9a2 - 25b2 = (3a)2 - (5b)2 = (3a - 5b)(3a + 5b) x3 - y3 = (x - y)(x2 + xy + y2) x3 + y3 = (x + y)(x2 - xy + y2) If n is a natural number xn - yn = (x - y)(xn-1 + xn-2y +...+ yn-2x + yn-1) If n is even (n = 2k) xn + yn = (x + y)(xn-1 - xn-2y +...+ yn-2x - yn-1) If n is odd (n = 2k + 1) xn + yn = (x + y)(xn-1 - xn-2y +...- yn-2x + yn-1) More Algebraic Formulas 2(a2 + b2) = (a + b)2 + (a - b)2 (a + b)2 - (a - b)2 = 4ab (a - b)2 = (a + b)2 - 4ab a4 + b4 = (a + b)(a - b)[(a + b)2 - 2ab]
