Answer:
The answer is
→ [tex]11x^2+3xy+y^2[/tex]
Step-by-step explanation:
Since were being asked to simplify, then that's what we should do.
[tex]12x^2+3xy-x^2+y^2[/tex]
[tex]=12x^2+3xy+-x^2+y^2[/tex]
Let's combine like terms.
[tex]=12x^2+3xy+-x^2+y^2[/tex]
[tex]=(12x^2+-x^2)+(3xy)+(y^2)[/tex]
[tex]=11x^2+3xy+y^2[/tex]
Therefore, [tex]11x^2+3xy+y^2[/tex] is your final simplifed answer.
Hope this helped! :^)
