Question

Q.. If x + 1 is a factor of x - 3ax + 3a + 13, then find the value of 'a'.​

Answer 1

Answer:

a = -2

Step-by-step explanation:

x+1=0

x = -1

if x+1 is a factor of  x - 3ax +3a +13 then the remainder is 0

x - 3ax +3a +13 =  (-1) - (3*a*-1)+ (3*a) +13 = 0

-1 +3a +3a +13=0

12+6 a= 0

6a= -12

a= -12/6

a = -2
