Answers
Answer:
-7
Step-by-step explanation:
x-2)6x²+ax+7(6x+12+a
6x²-12x
12x +ax+7
(12+a)x -24-2a
31+2a
31+2a=3
a= -28/2
a= -14
half of a = -7
Answer:
a= -14 half of a = -7
Step-by-step explanation:
6x +(a+12)
x-2 6x2 +ax + 7
6x2-12x
-----------
(a+12)x+7
(a+12)x-2(a+12)
------------------
7+2(a+12)
Given remainder is 3
7+2(a+12) = 3
7+2a +24 =3
2a +31 = 3
2a = 3-31
2a = -28
a = -14
Half of a = -7
