Answer 2

To simplify the expression (a + 7)*(a + 2) and raise it to the power of 2, we can follow these steps:

Step 1: Expand the expression (a + 7)*(a + 2) using the distributive property: (a + 7)*(a + 2) = a*(a + 2) + 7*(a + 2)

Step 2: Multiply each term inside the parentheses: a*(a + 2) + 7*(a + 2) = a*a + a*2 + 7*a + 7*2

Step 3: Simplify each term: a*a + a*2 + 7*a + 7*2 = a^2 + 2a + 7a + 14

Step 4: Combine like terms: a^2 + 2a + 7a + 14 = a^2 + 9a + 14

Step 5: Raise the simplified expression to the power of 2: (a^2 + 9a + 14)^2

The final simplified expression raised to the power of 2 is (a^2 + 9a + 14)^2.
