Solution: The expression we want to factorize is a 3 +b3 +c3 −3abc. To simplify it, we'll use the identity: (x + y) 3 = x3 + y3+ 3xy(x + y) · In our case, we can see that: So, we have: a 3 + b3 + c3 - 3abc = (a + b)3 + c3- 3abc · Now, let's factorize the expression (a + b) 3 + c. Now, let's factorize the expression (a + b) 3 + c3 - 3abc using the identity: (x + y) 3 = x3 + y3 + 3xy(x + y) · In our case: So, we can rewrite the expression as: (a + b) 3 + c3 - 3abc = (a + b + c)((a + b)2 - (a + b)c + c2) - 3abc ...
