The question states that p(3)=−2, So it must be true that.. (insert the true equation here)

kaydademon:

2=p(3)=(3+k)q(3)+r ?

xxemilianaxx:

Good, Now we can plug in all the possible answers. If the answer is A, B, or C, r will be 0, while if the answer is D, r will be −2. A. −2=p(3)=(3+(−5))q(3)+0 − 2=(3−5)q(3) −2=(−2)q(3) This could be true but, Only if what?

xxemilianaxx:

Apologies I messed up a bit A. −2=p(3)=(3+(−5))q(3)+0 -2=(3−5)q(3) −2=(−2)q(3)

kaydademon:

its okay but it would be true if q(3)=-2

xxemilianaxx:

Try that again

kaydademon:

-1?

xxemilianaxx:

No, But close

kaydademon:

oh wait i see its 1

xxemilianaxx:

Yes

xxemilianaxx:

B. −2=p(3)=(3+(−2))q(3)+0 −2=(3−2)q(3) −2=(−1)q(3) This could be true if

kaydademon:

q(3)=.2

xxemilianaxx:

.2?

kaydademon:

mb i just meant 2

xxemilianaxx:

Mhm, Now this might get a little tricky if you don't do the math right. C. −2=p(3)=(3+2)q(3)+0 −2=(5)q(3) This would be true if?

kaydademon:

q(3)= 2/5 i did it im just making sure its right and trying to learn to do it more

xxemilianaxx:

I see, You keep confusing your positives with negatives lol

xxemilianaxx:

Try it again and take your time, No rush

kaydademon:

q(3)= −2/5

xxemilianaxx:

Great, D. −2=p(3)=(3+(−3))q(3)+(−2) −2=(3−3)q(3)+(−2) −2=(0)q(3)+(−2) This will always be true no matter what q(3) is

kaydademon:

Of the answer choices the only one that is true about p(x) is D when the remainder when p(x) is divided by x−3 is -2 so then D is correct one?

xxemilianaxx:

It is

xxemilianaxx:

That's it right?

kaydademon:

ima post another q
