(3x+2k)^3+(4x-7)^2 has a remainder of 33 when divided by x-3. find k.

i tried to expand the expression, but i don't get a polynomial, so how do i apply the remainder theorem? i would really appreciate it if anyone could tell me how to solve this question! thanks!

**Reiny**, Monday, January 14, 2008 at 8:42amYou do not have to expand it,

the remainder theorem would say here that

f(3) = 33, so

(9+2k)^3 + (12-7)^2 = 33

(9+2k)^3 = 8 , take the cube roo

9+2k = 2

2k = -7

k = -7/2
