You can put this solution on YOUR website! Find the product. (4m+2n)^2
= (4m+2n)*(4m+2n)
= 4m*(4m+2n) + 2n(4m+2n)
=
=
--------------------------
a = 4m, b = 2n
You can put this solution on YOUR website! Find the product. (4m+2n)^2
--------------------------------
(4m+2n)(4m+2n)
Use FOIL:
F: 16m^2
O: 8mn
I: 8mn
L: 4n^2
-----------------
Combine to get:
16m^2+16mn+4n^2
