Write f(x) in the form (x-k)q(x)+r, given that k=-2. f(x)=3x^4+4x^3-10x^2+15
1 answer:
You may perform the division using either long division or synthetic division. Any preference?
I used synthetic div. with -2 as the divisor:
________________
-2 / 3 4 -10 0 15
-6 4 12 -24
-------------------------
3 -2 -6 12 -9
In factored form, with remainder, we then have:
(x+2)(3x^3 - 2x^2 - 6x + 12) remainder -9
If you need clarification of any part of this solution, let me know.

Answer: B is what 6 x +4 = to 4bx - 2 is 6x plus 4 = to 24 then 4bx - 2 is YA so b is Y
It is just 18 :)It is just 18 :)
Using 5*6=30, you can add 6 to the 30, which equals 36.
SO just add 6 to your answer of 5*6, the answer you will get is 36.
