Determine, if possible, if (y – 1) is a factor (y3 – 9y2 + 10y +5).

a. no
b. yes
c. only if x = –1
d. not enough information to determine

Option A.

Step-by-step explanation:

We have and (y-1) is a factor of P(y) if and only if P(1)=0, this means if:

y-1=0

y=1

Now we have to replace y=1 in this is:

Then this means that (y-1) isn't a factor of .

And the correct option is A.
