The correct Answer is:
To find the square of \( (2x + 3y) \), we can use the algebraic identity for the square of a binomial. The identity states: \[ (a + b)^2 = a^2 + b^2 + 2ab \] In our case, we can let: - \( a = 2x \) - \( b = 3y \) Now, we can apply the formula step by step. ### Step 1: Identify \( a \) and \( b \) Here, we have: - \( a = 2x \) - \( b = 3y \) ### Step 2: Apply the formula Using the formula \( (a + b)^2 = a^2 + b^2 + 2ab \), we can substitute \( a \) and \( b \): \[ (2x + 3y)^2 = (2x)^2 + (3y)^2 + 2(2x)(3y) \] ### Step 3: Calculate \( a^2 \) Calculate \( (2x)^2 \): \[ (2x)^2 = 4x^2 \] ### Step 4: Calculate \( b^2 \) Calculate \( (3y)^2 \): \[ (3y)^2 = 9y^2 \] ### Step 5: Calculate \( 2ab \) Calculate \( 2(2x)(3y) \): \[ 2(2x)(3y) = 2 \cdot 2 \cdot 3 \cdot xy = 12xy \] ### Step 6: Combine the results Now, combine all the results together: \[ (2x + 3y)^2 = 4x^2 + 9y^2 + 12xy \] Thus, the final answer is: \[ (2x + 3y)^2 = 4x^2 + 9y^2 + 12xy \] ---
