a ^2 - a + 12

Answer 1

C.) -a^2 - a + 12

Explanation:

(-a + 3) (a + 4)

FOIL (First, Outer, Inner, Last)

-a * a = -a^2

-a * 4 = -4a

3 * a = 3a

3 * 4 = 12

-4a + 3a = -a

Answer 2

C.) -a^2 - a + 12

Explanation:

(-a + 3) (a + 4)

FOIL (First, Outer, Inner, Last)

-a * a = -a^2

-a * 4 = -4a

3 * a = 3a

3 * 4 = 12
