To complete the polynomial subtraction equation, we need to subtract the second expression from the first expression. Here is how it looks:

  1. The first expression is:
    \( 9x^2 + x + 13 \)

  2. The second expression is:
    \( 2x^2 + 12x + (x^2 + 5x + 2) \)

Now, let's simplify the second expression before proceeding with the subtraction:

  • Combine the terms in the second expression: \[ 2x^2 + 12x + x^2 + 5x + 2 = (2x^2 + x^2) + (12x + 5x) + 2 = 3x^2 + 17x + 2 \]

Now we can write the polynomial subtraction equation:

  • So, we need to subtract: \[ 9x^2 + x + 13 - (3x^2 + 17x + 2) = (9x^2 - 3x^2) + (x - 17x) + (13 - 2) \]

Now we simplify that: \[ (9 - 3)x^2 + (1 - 17)x + (13 - 2) = 6x^2 - 16x + 11 \]

Putting it all together, the filled equation is: \[ 9x^2 + x + 13 - (2x^2 + 12x + (x^2 + 5x + 2)) = 6x^2 - 16x + 11 \]

Thus, the complete equation with the blanks filled is: \[ 9x^2 + x + 13 - (2x^2 + 12x + 2) = 6x^2 - 16x + 11 \]
