Answer:
[tex]3x^2-x+3[/tex]
Step-by-step explanation:
[tex](x^2+3x+2)+(2x^2-4x+1)[/tex]
Now we open the brackets first
[tex]x^2+3x+2+2x^2-4x+1[/tex]
We take the like terms together
Like terms are those terms which have same degree of x with them. Constant terms are also like terms
[tex]x^2+2x^2+3x-4x+1+2[/tex]
Simplifying the like terms
[tex]3x^2-4x+3[/tex]
Hence this is our answer
