To simplify the expression \((-10x^2 - 7x + 4) + (-6x + 9)\), you can combine like terms:
1. First, rewrite the expression:
\[
-10x^2 - 7x + 4 - 6x + 9
\]
2. Next, combine the like terms:
- For the \(x^2\) term: \(-10x^2\) (this is the only one)
- For the \(x\) terms: \(-7x - 6x = -13x\)
- For the constant terms: \(4 + 9 = 13\)
3. Putting it all together, we get:
\[
-10x^2 - 13x + 13
\]
Thus, the simplified expression is:
\[
-10x^2 - 13x + 13
\]
