The correct Answer is:
To find the LCM of the polynomials \( A \) and \( B \), we will follow these steps: ### Step 1: Identify the polynomials We have: - \( A = (x + 3)^2 (x - 2) (x + 1)^2 \) - \( B = (x + 1)^2 (x + 3) (x + 4) \) ### Step 2: Factor the polynomials The factors of \( A \) are: - \( (x + 3)^2 \) - \( (x - 2) \) - \( (x + 1)^2 \) The factors of \( B \) are: - \( (x + 1)^2 \) - \( (x + 3) \) - \( (x + 4) \) ### Step 3: Determine the highest power of each factor Next, we identify the highest power of each factor present in both polynomials: - For \( (x + 3) \): - In \( A \), the power is \( 2 \). - In \( B \), the power is \( 1 \). - **Take the maximum**: \( (x + 3)^2 \) - For \( (x - 2) \): - In \( A \), the power is \( 1 \). - In \( B \), it is not present (power \( 0 \)). - **Take the maximum**: \( (x - 2)^1 \) - For \( (x + 1) \): - In \( A \), the power is \( 2 \). - In \( B \), the power is \( 2 \). - **Take the maximum**: \( (x + 1)^2 \) - For \( (x + 4) \): - In \( A \), it is not present (power \( 0 \)). - In \( B \), the power is \( 1 \). - **Take the maximum**: \( (x + 4)^1 \) ### Step 4: Write the LCM Now we combine all the factors with their highest powers to write the LCM: \[ \text{LCM}(A, B) = (x + 3)^2 (x - 2) (x + 1)^2 (x + 4) \] ### Step 5: Final expression Thus, the LCM of the polynomials \( A \) and \( B \) is: \[ \text{LCM}(A, B) = (x + 3)^2 (x - 2) (x + 1)^2 (x + 4) \]
