Let the number of geese be x.
Then number of goats is 22-x.
A goose has 2 legs, and a goat has 4.
There are a total of 82 legs.
So,
2x + 4(22-x) = 82
2x + 88 - 4x = 82
-2x = -6
x = 3
There are 3 geese and (22-3=) 19 goats.

B² - 4ac
= 8² - 4*(-2)*(-9)
= 64 - 72
= -8
There are 7 numbers.
Each number can be paired with the remaining 6 numbers.
7 x 6 = 42 different two digit numbers can be made.
