7a) f(x0 = 2x3+32-6x+1
Find the remainder when F(x) is divided by (2x-1)
b) (i) Find the remainder when f(x) is divided by (x+2)
(ii) Hence, or otherwise solve the equation: 2x3+32-6x-8=0
giving your answer to two decimal places.
This is what I've done:
a) r= -1 (i did f(1/2) to get that)
b) (1) r = 9 ( i did f(-2) for that)
could someone please help me with part (ii)?
