Two polynomials P and D are given. Use either synthetic or long division to divide
P(x)
by
D(x),
and express P in the form
P(x) = D(x) · Q(x) + R(x).
P(x) = 4x^5 + 16x^4 − 16x^3 − x − 5, D(x) = x2 − 4

What I got was $$(x^2-4)(4x^4+24x^3+64x^2128x+255)+505$$
Its reading it as wrong

anonymous · Answer

which method did you use?

anonymous · Answer

synthetic division

anonymous · Answer

you cannot
the degree of the denominator is 2

anonymous · Answer

if you divide a polynomial of degree 5 by a polynomial of degree 2, you will get a polynomial of degree $5-2=3$

anonymous · Answer

Wait I'm confused.

anonymous · Answer

i used long division and got f(x)=(x^2-4)(4x^3+16X^2+64)-(251-x)?

anonymous · Answer

Can you show me how you divided it? If possible.
