Algebra Formulas

• (a + b) 2 = a 2 + b 2 + 2ab.
• (a − b) 2 = a 2 + b 2 − 2ab.
• a 2 − b 2 = (a − b) (a + b)
• (x + a) (x + b) = x 2 + (a + b) x + ab.
• (a + b + c) 2 = a 2 + b 2 + c 2 + 2ab + 2bc + 2ca.
• (a + (−b) + (−c)) 2 = a 2 + (−b) 2 + (−c) 2 + 2a (−b) + 2 (−b) (−c) + 2a (−c) (a – b – c) 2 = a 2 + b 2 + c 2 − 2ab + 2bc − 2ca.
