To complete the polynomial equation, we will subtract the second expression from the first and determine the resulting difference.
Given the first expression: \( 9x^2 + x + 13 \)
And the second expression: \( 2x^2 + 12x + (x^2 + 5x + 2) \)
First, we need to combine the terms of the second expression:
-
Combine the \( x^2 \) terms:
- \( 2x^2 + x^2 = 3x^2 \)
-
Combine the \( x \) terms:
- \( 12x + 5x = 17x \)
-
The constant term remains \( 2 \).
Thus, the second expression simplifies to: \( 3x^2 + 17x + 2 \)
Now, we can perform the subtraction: \[ (9x^2 + x + 13) - (3x^2 + 17x + 2) \]
Distributing the negative sign across the terms of the second expression: \[ 9x^2 + x + 13 - 3x^2 - 17x - 2 \]
Now, combine like terms.
-
For \( x^2 \) terms:
- \( 9x^2 - 3x^2 = 6x^2 \)
-
For \( x \) terms:
- \( x - 17x = -16x \)
-
For constant terms:
- \( 13 - 2 = 11 \)
Therefore, the resulting expression after subtracting is: \[ 6x^2 - 16x + 11 \]
Now we can fill in the blanks:
- The term representing the missing expression after subtraction is \( 3x^2 + 17x + 2 \).
- The resulting difference is \( 6x^2 - 16x + 11 \).
So the completed polynomial equation is: \[ 9x^2 + x + 13 - (3x^2 + 17x + 2) = 6x^2 - 16x + 11 \]
