Hi
Note FOIL method: basically a question of combining 4 independent multiplications
(t+1)(t+4)= t^2 + 5t + 4
F	First terms     t*t OR t^2
O	Outside terms    {{{highlight(4*t)}}}
I	Inside terms     {{{highlight(1*t)}}}
L	Last terms       1*4 OR 4
                    t^2 + 5t + 4    combining like terms
