Answer:


36n^2+12n+1

Explanation:

Foil the equation!

1. You see that is to the second power so it means this
(6n+1)*(6n+1)

2. Then you use the Foil method. First, Outside, Inside, and Last.

3. Combined like terms

4. Answer!

A tip you can use to avoid Foil is this mental math trick: (Keep in mind this only works if the polynomial is being squared.)

1. Multiply the first number by itself =
6n *6n = 36n^2

2. Add the first number by itself =
6n+6n = 12n

3. Multiply the last number by itself =
1*1 =1

4. Combined to form your answer =
36n^2+12n+1

NOTE: This is the same thing as a foil but it uses mental math so it takes less time!
