Question

Can someone please help me with this question?
Use synthetic division! Create your own third degree polynomial that when divided by x + 2 has a remainder of –4.

Answer 1

Will this one work?
x^3+2x^2-4? if it will can someone please work it out? i worked it out and everything but i dont know how to word it for the answer

Answer 2

dividend=divisor *quotient + remainder
third degree polynomial=(x + 2 ) *quotient+–4.
as we need to get a hird degree polynomia quotient can be in terms of x^2
exapmle is (x + 2 ) *x^2–4.
x^3+2x^2–4.

Answer 3

yes ur ans is crrct

Answer 4

how would you write it as an answer?

Answer 5

because the last four numbers i got was 1 0 0 -4 but you can't write it as x^2+0x+0-4/x+2 can you?

Answer 6

dividend=divisor *quotient + remainder is the formula

Answer 7

As an answer to the question or to the division?

Answer 8

Can you help me with this one?
Let f(x) = x4 – 8x3 + 16x2 – 19 and g(x) = x – 5. Find f(x) over g(x)


Answer to the question

Answer 9

like the final answer

Answer 10

Then you would put x^2 -4/x+2; you don't need to put the ones that are zero. And the x+2 is just under the 4

Answer 11

Would it be wrong if i did?

Answer 12

No, but it isn't necessary

Answer 13

ok thank you!
