You must FOIL (first, outside, inside, last)

First (The first number/variable of each parentheses must be multiplied together)

(a + 3)(a - 2)


a^(2)

Outside (The outside number/variable of each parentheses must be multiplied together)

(a + 3)( a - 2)

-2a

Inside (The inside number/variable of each parentheses must be multiplied together)

(a + 3)(a - 2)

3a

Last (The last number/variable of each parentheses must be multiplied together)

(a + 3)( a - 2)

-6

Now add/subtract each FOIL answer according to its sign


a^(2) - 2a + 3a - 6

Combine like terms


a^(2) + a - 6

Hope this helped!
