FOIL



      (x  +  3)(x  +  5)

       F        F



      (x  +  3)(x  +  5)

       |              |

        \   outer    /







      (x  +  3)(x  +  5)

             |  |

            Inner







      (x  +  3)(x  +  5)

             |        |

              \ Last /





   First+ Outer+ Inner+ Last

   x(x) + x(5) + 3(x) + 3(5)



    x^2 + 5x + 3x + 15



Combine like terms



     x^2 + 8x + 15
