Question

what is the remainder when x^2+5 is divided by x+1??

Answer 1

do it in your head
put \(x=-1\) and get \((-1)^2+5=6\)

Answer 2

so the remainder is 6??

Answer 3

if \(p(x)\) is divided by \(x-a\) the remainder is \(p(a)\)

Answer 4

oh ok that makes sense.

Answer 5

you could do the long division of you like, but since you were only asked for the remainder, that is all you need

Answer 6

thank you
