To correctly fill in the blanks for the polynomial equation that shows the subtraction of the second expression from the first, we start with the two expressions provided.
First Expression:
\[
9x^2 + x + 13
\]
Second Expression:
\[
2x^2 - 12x + (blank\ 1) \
\]
Now we write the subtraction:
\[
(9x^2 + x + 13) - (2x^2 + 12x + (blank\ 1))
\]
Steps to Solve:
-
Distribute the negative sign:
\[
9x^2 + x + 13 - 2x^2 - 12x - (blank\ 1)
\]
-
Combine like terms:
- For \(x^2\): \(9x^2 - 2x^2 = 7x^2\)
- For \(x\): \(x - 12x = -11x\)
- For constant: \(13 - (blank\ 1)\)
Fill in the Blanks:
So, we need the resulting difference after performing the subtraction \(9x^2 + x + 13 - (2x^2 + 12x + (blank\ 1))\).
From our earlier calculation, after subtraction, we have:
\[
7x^2 - 11x + (13 - (blank\ 1))
\]
We will assume that the constant from the second polynomial is 0 for the blanks to be filled.
If we want to set the resulting constant term to be equal to 2 (as stated in the question), then we should solve the equation:
\[
13 - (blank\ 1) = 2 \
(blank\ 1) = 11
\]
Final polynomial equation filled in:
Putting all the blanks together, we have:
\[
9x^2 + x + 13 - (2x^2 + 12x + 11) = 7x^2 - 11x + 2
\]
Result
- The first blank should represent the constant from the second expression: 11
- Confirming the resulting terms from subtraction, the resulting difference from the first polynomial minus the revised second polynomial would give:
Hence, the complete polynomial equation that shows the subtraction is:
\[
9x^2 + x + 13 - (2x^2 + 12x + 11) = 7x^2 - 11x + 2
\]
Your filled answers will look like this:
- First Polynomial: \(9x^2\)
- x: \(x\)
- 13: \(13\)
- Subtracted: \(2x^2\)
- 12x: \(12x\)
- (Blank for constant): \(11\) (to represent the constant \(+11\))
- Resulting \(x^2\): \(7x^2\)
- Resulting \(x\): \(-11x\)
- Resulting Constant: \(2\)
Thus, the final polynomial equation is:
\[
9x^2 + x + 13 - (2x^2 + 12x + 11) = 7x^2 - 11x + 2
\]
