Question

Check whether X-2 is a factor of xcube-4xsquare+x+6 using factor theorem​

Answer 1

Answer:

No

Step-by-step explanation:

g(x)= x-2

Let g(x)=0

Therefore,x-2=0

or,x=2

Let f(x)=x3+4x2+x+6

Therefore, f(2)=2^3+4×(2^2)+2+6

or,8+16+2+6=32

As the resultant is 32 and not 0 so x-2 is not a factor of f(x).
