Use F.O.I.L.
First
Outside
Inside
Last
First is 4s * s
4s * s = 4s^2
Outside is 4s *3
4s * 3 = 12s
Inside is 2 * s
2 * s = 2s
Last is 2*3
2 *3 is 6
Now arrange them in that order
4s^2 + 12s + 2s +6
as you can see, we can simplify this equation even more, as there are to things multiplied by s
We add 12s and 2s to make 14s
Your answer is 4s^2 + 14s + 6
Hope I helped!
