Find k if the remainder is 15 in (x^3-7x^2+kx+27)/(x-2)please show me step by step

OpenStudy (inkyvoyd):

I once knew how to do this, but then I took an arrow to the knee.

OpenStudy (anonymous):

lol. you do this by using long division, or at least i would

OpenStudy (anonymous):

i would answer but I don't want to type out each step

OpenStudy (inkyvoyd):

Syntheic division.

OpenStudy (inkyvoyd):

only about five times faster.

OpenStudy (inkyvoyd):

treat k as a constant

OpenStudy (anonymous):

isn't synthetic division only useful for finding zeros?

OpenStudy (inkyvoyd):

Uhm, no, it's a shortcut to division when the coefficient is 1

OpenStudy (inkyvoyd):

it's like, 20 times faster than synthetic division if your polynomial gets large enough.
