what is the product of (- a + 3)( a + 4)?
a ^2 - a - 12 not this one
-a ^2 - a - 12
-a ^2 - a + 12
a ^2 - a + 12

C.)   -a^2 - a + 12

Step-by-step 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

-a^2 - a + 12

C.)   -a^2 - a + 12

Step-by-step 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
