Factorise using suitable identity a^3+b^3-1+3ab |
|
Answer» y, you MIGHT have asked the wrong QUESTION, but here are some useful identities that you can use these identities : (a + b)^3 = a^3 + b^3 + 3ab (a + b) (a – b)^3 = a^3 – b^3 – 3ab (a – b)a^3 + b^3 = (a + b)(a^2 + b^2 - ab)a^3 - b^3 = (a - b)(a^2 + b^2 + ab) |
