Algebra Formulas

The important algebra formulas used in Algebra are.

$(a + b)^2 = a^2 + 2.a.b + b^2$

$a^2 + b^2 = (a + b)^2 - 2.a.b$

$(a - b)^2 = a^2 - 2.a.b + b^2$

$a^2 + b^2 = (a - b)^2 + 2.a.b$

$(a + b + c)^2 = a^2 + b^2 + c^2 + 2.(a.b + b.c + c.a)$

$(a + b)^3 = a^3 + b^3 + 3.a.b.(a + b)$

$a^3 + b^3 = (a + b)^3 - 3.a.b.(a + b)$

$(a - b)^3 = a^3 - b^3 - 3.a.b.(a − b)$

$a^3 - b^3 = (a − b)^3 + 3.a.b.(a − b)$

$a^2 - b^2 = (a + b).(a − b)$

$a^m.a^n=a^{m+n}$

$\frac{a^m}{a^n}=a^{m-n}$

$(a^m)^n=a^{mn}$
