Answer:
4. [tex]4x^{2} +2x-2[/tex]
Step-by-step explanation:
To add these two equations together, you have to combine like terms.
1. [tex]x^{2} +3x^{2} = 4x^{2}[/tex]
2. [tex](-3x)+5x = 2x[/tex]
3. 7 - 9 = -2
Then you just combine all of these terms together into one equation and you have your answer.
