Answer:
[tex]x^{2}[/tex]+5x+6.
Step-by-step explanation:
Here you can use the foil method.
1. Multiply x by x to get [tex]x^{2}[/tex].
2. Multiply x by 3 to get 3x.
3. Multiply 2 by x to get 2x.
4. Multiply 2 by 3 to get 6.
Now, you have to add all those terms to get [tex]x^{2}[/tex]+3x+2x+6 and you can simplify that to [tex]x^{2}[/tex]+5x+6.
