Answer:
The answer is [tex]5x^2-7x+15[/tex]
Step-by-step explanation:
In order to determine the final expression, we have to know about adding similar terms.
When we add similar terms, firstly we have to find the amount of different terms. A term is basically the variable and its power.
In this case, there are 3 terms:
- [tex]x^2[/tex]
- [tex]x[/tex]
- [tex]number[/tex]
Then, we add similar terms:
[tex](6x^2-4x+11)+(4-x^2-3x)\\(6x^2-x^2)+(-4x-3x)+(11+4)\\5x^2-7x+15[/tex]
Finally, the final expression is [tex]5x^2-7x+15[/tex]
