7a) f(x0 = 2x(adsbygoogle = window.adsbygoogle || []).push({}); ^{3}+3^{2}-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: 2x^{3}+3^{2}-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)?
