What are the basic formulas of algebra?

The basic algebraic formulas are:

• [latex]a2– b2 = (a – b) (a + b)[/latex]
• (a + b)2= a2 + 2ab + b.
• a2+ b2 = (a – b)2 + 2ab.
• (a – b)2= a2 – 2ab + b.
• (a + b + c)2= a2 + b2 + c2 + 2ab + 2ac + 2bc.
• (a – b – c)2= a2 + b2 + c2 – 2ab – 2ac + 2bc.
• (a + b)3= a3 + 3a2b + 3ab2 + b.
• (a – b)3= a3 – 3a2b + 3ab2 – b.
