First
Outside
Inside
Last
multiply both of the first terms 2c x 5c
then do the outsides of the terms 2c x -7
then the insides -1 x 5c
then the lasts -1 x -7
now add them all together
10

- 14c - 5c + 7 = 10

- 19c + 7
(2c - 1)(5c - 7)
2c(5c - 7) - 1(5c - 7)
2c(5c) - 2c(7) - 1(5c) - 1(-7)
10c² - 14c - 5c + 7
10c² - 19c + 7
