Question

if x+1 is a factor of ax3+x-2x+4a-9,find the value of a

Answer 1

this is your and for your question

Answer 2

Answer:

p(x)= ax3+x-2x+4a-9

g(x)= x+1

g(1)= x = -1

p(1)= a(-1)3 + (-1) - 2x + 4a -9 = 0

     = -a -1 + 2 + 4a- 9 = 0

     = 3a - 8= 0

     = 3a = 8

     = a = 8/3

hope it helps
