Can someone please determine q(x) and r(x) as described by the division algorithm such that f(x)=g(x)q(x) + r(x) so that i can check my answers for the following:
a. f(x)= x^6+3x^5+4x^2-3x+2 and g(x)= x^2+2x-3
and
b. f(x0=x^6+3x^5+4x^2-3x+2 and g(x)= 3x^2+2x-3
Cheers

Since you just want a check on your answers, I'll skip all the tedious working out (especially since it's hard to format properly in text):
a. q(x) = x^4 + x^3 + x^2 + x + 5
r(x) = -10x + 17.
b. q(x) = (1/3)x^4 + (7/9)x^3 - (5/27) x^2 + (73/81) x + 133/243
r(x) = -(338/243) x + 295/81.
I've checked both these answers - just as well, since I'd originally made a mistake in each.
