 (x+7) (x+9)
  ^     ^
  |     |
  +--F--+

 (x+7) (x+9)
  ^       ^
  |       |
  +---O---+

 (x+7) (x+9)
    ^   ^
    |   |
    +-I-+

 (x+7) (x+9)
    ^     ^
    |     |
    +--L--+

So using FOIL to multiply we get:
x%2Ax+%2B+x%2A9+%2B+7%2Ax+%2B+7%2A9
which simplifies as follows:
x%5E2+%2B+9x+%2B+7x+%2B+63
x%5E2+%2B+16x+%2B+63
