Best ResponseYou've already chosen the best response.0Remember FOIL, First, Outside, Inside, Last. \[(7p8)(7p+8)\] First \[7p*7p = 49p^{2}\] Outside \[7p*8 = 56p\] Inside \[8*7p = 56p\] Last \[8*8 = 64\] Add all these up \[49p^{2}+56p56p64 = 49p^{2}64\] This also helps where if you have the form \[(Ax+b)(Axb) = A^{2}x^{2}  b^{2}\]
