You can put this solution on YOUR website!
1.(3s+3)squared
= (3s+3)*(3s+3)
= 3s*(3s+3) + 3*(3s+3)
= 9s%5E2+%2B+9s+%2B+9s+%2B+9
= 9s%5E2+%2B+18s+%2B+9
--------------------
Do the others the same way.
-------------
2.(5z+1)squared
3.(10y+1)squared
4.(1+10y)squared
=================
3 & 4 are the same.
10y+1 = 1+10y
