Question

let p(x)=x4+2x3-2x3-x2+2x+8,then which one of the following can never be a factor of p(x)​

Answer 1

Answer:

let us take (x-1) as a factor then,

x-1=0

x=1

substitute X value in p(x)

p(1)=1+2-2-1+2+8

p(1)=10

here

p(1)≠0

.

. . p(1) will never be as a factor

I hope this answer may help you dear
