Question

if x+1 is a factor of x (2) - 3ax+3a-7 then find the value of a??

Answer 1

put the valu in x=-1
inthe eqn and thats will be equal to 0
and the answer which will be come out with this will be 3/2

Answer 2

Answer:

from,x+1

If,x+1=0

So,x=-1

Now,put the value of x in that equation,

(1)^2-3a(-1)+3a-7=0

1+3a+3a-7=0

6a-6=0

a=1.
