D = Division

M = Multiplication

A = Addition

S = Subtraction

Basic Algebra Formulas

1 na2 – b2 = (a – b)(a + b)

2 (a + b)2 = a2 + 2ab + b2

3 a2 + b2 = (a + b)2 – 2ab

4 (a – b)2 = a2 – 2ab + b2

Real Numbers 

1 √ab = √a √b

2 √(a/b) = √a / √b

3 (√a + √b) (√a – √b) = a – b

4 (√a + √b)2 = a + 2√ab + b

Algebra Formulas

1 (a + b)2 = a2 + 2ab + b2

2 (a – b)2 = a2 – 2ab + b2

3 (a + b) (a – b) = a2 – b2

4 (x + a)(x + b) = x2 + (a + b)x + ab

5 (x + a)(x – b) = x2 + (a – b)x – ab

Trigonometry Formulas

1 sin-1(-x) = – sin-1x

2 tan-1x + cot-1x = π / 2

3 sin-1x + cos-1 x = π / 2
