FOIL is short for First, Outside, Inside, Last
It helps you to remember all the combinations when multiplying two bracketed terms each containing two expressions.
For your example, we have
First : (cc)=c2
Outside: (c* -7)=-7c
Inside: (9*c)=9c
Last: (9*-7)=-63
Add these together to get the answer:
(c+9)(c-7)
(=F+O+I+L)
=c27c+9c63
=c2+2c63
