iF i helped you then please fan and give me a medal!

Answer 5

only possible rational roots are 1 or -1

plug in each to see which one works

Answer 6

if x=1 works then factor is " x-1"

if x =-1 works then factor is "x+1"

if both work then factor is "x^2 -1" --> x^2-1 = (x-1)(x+1)

Answer 7

plug it in for x right?

Answer 8

yes and see if you get y=0

Answer 9
