a^3 + 3ab (a+b) + b^3 _____?
a^3 + 3ab (a+b) + b^3 _____?
Explanation
The expression a^3 + 3ab(a+b) + b^3 simplifies to (a + b)^3.
This follows from the expansion of (a + b)^3, which is a^3 + 3a^2b + 3ab^2 + b^3.
The expression a^3 + 3ab(a+b) + b^3 simplifies to (a + b)^3.
This follows from the expansion of (a + b)^3, which is a^3 + 3a^2b + 3ab^2 + b^3.
