Algebra formula(बीजगणित के सूत्र) ( a + b )² = a ² + 2 ab + b ² ( a – b )² = a ² – 2 ab + b ² ( a – b )² = ( a + b )² – 4 ab ( a + b )² = ( a – b )² + ( a – b )² + 4 ab a ² + b ² = ( a + b )² – 2 ab a ² + b ² = ( a – b ) + 2 ab a ² – b ² = ( a + b ) ( a – b ) ( a + b )³ = a ³ + 3 a ² b +3 ab ² + b ³ ( a – b )³ = a ³ + b ³ + 3 ab ( a + b ) ( a – b )³ = a ³ – 3 a ² b + 3 ab ² – b ³ ( a – b )³ = a ³ – b ³ -3 ab ( a – b ) a ³ – b ³ = ( a + b ) ( a ² – ab + b ²) a ³ + b ³ = ( a + b )³ – 3 ab ( a + b ) a ³ – b ³ = ( a – b ) ( a ²+ ab ...
