The question is asking us to find the sum. To do this, let's first write the original equation and then take it from there.
[tex](3 x^{2} + 3x - 5) + (-7 x^{2} + 9)[/tex]
Use distributive property:
[tex]3 x^{2} + 3x - 5 - 7 x^{2} + 9[/tex]
Combine Like Terms:
[tex] -4 x^{2} +3x+4[/tex]
Therefore, the answer to your question is -4x² + 3x + 4. Hope this helps and have a fantastic day!
