Work Step by Step

To find the least common multiple (LCM), we factor the polynomials completely and the LCM is the product of each of these factors raised to the greatest power that occurs in the polynomials. So we have $$ x^2+4x+4=(x+2)^2 \\ x^3+2x^2=x^2(x+2),\\ (x+2)^3 .$$ Thus, the LCM is $x^2(x+2)^3$.
