2
+2x+4.



Solve the problem just like the example below
⬇️
Perform the operation.
left parenthesis, x, plus, 9, right parenthesis, plus, left parenthesis, 3, x, squared, plus, 4, x, minus, 2, right parenthesis

(x+9)+(3x
2
+4x−2)
x, plus, 9, plus, 3, x, squared, plus, 4, x, minus, 2
x+9+3x
2
+4x−2

Combine like terms: 3, x, squared, plus, 5, x, plus, 7
3x
2
+5x+7

Answer 1

To find the sum of \(-8x - 3\) and \(-7x^2 + 2x + 4\), we'll perform the operation as follows:

1. Write out the expression:
\[
(-8x - 3) + (-7x^2 + 2x + 4)
\]

2. Rearranging and grouping all terms together:
\[
-8x - 3 - 7x^2 + 2x + 4
\]

3. Now, we can combine like terms:
- For \(x\) terms: \(-8x + 2x = -6x\)
- For constant terms: \(-3 + 4 = 1\)
- The \(x^2\) term: \(-7x^2\) (only one term)

4. Combine all these results:
\[
-7x^2 - 6x + 1
\]

So, the final result is:
\[
-7x^2 - 6x + 1
\]
