Im not going to go in too much detail about how I solved each one, just because there a lot of blanks, but the general process is to just subsitute these numbers in for x:
1st column
3^2 = 9
4^2 = 16
5^2 = 25
6^2 = 36
2nd column
1 + 4 = 5
4 + 4 = 8
9 + 4 = 13
16 + 4 = 20
3rd column(same as the 1st one because it is just the expanded form of the first expression)
