What is the formula of (x+y+z)^3
What is the formula of (x+y+z)^3- (x^3y^3)=(xy)(x^2xyy^2) This is a sum of cubes This is a semiimportant identity to know (x^3y^3)=(xy)(x^2xyy^2) Although it doesn't apply directly to this question, it's also important to know that (x^3y^3)=(xy)(x^2xyy^2) This gives us the rule (x^3y^3)=(xy)(x^2∓xyy^2)Writing any polynomial directly just requires listing all possible exponent combinations of a^x*b^y*c^z where every term has xyz=3 and the coefficient of each term is (xyz)!/(x!y!z!) This works for any length polynomial and in this case we would have a^3 b^3 c
