Answer:

[tex]9s^{2}[/tex]+6st+[tex]t^{2}[/tex]

Step-by-step explanation:

If it's binomial it would mean 2 so

(3s+t) (3s+t)

Times 3s and 3s = [tex]9s^{2}[/tex]

Times 3s and t= 3st or 3ts according to the alphabet order

then t times 3s= 3st

lastly t times t = [tex]t^{2}[/tex]

[tex]9s^{2}[/tex]+[tex]3st^{2}[/tex]+[tex]3st^{2}[/tex]+[tex]t^{2}[/tex]= [tex]9s^{2}[/tex]+6st+[tex]t^{2}[/tex]
