Question

anonymous · Answer

Do synthetic division.

anonymous · Answer

$$
f(x)=2x^3–8x^2+6x–36
$$
Compute f(4) and this will give you the remainder.

anonymous · Answer

D: Omg. I never knew that shortcut.

anonymous · Answer

Yes if f(a) =0 then f(x) is divisible by x-a

anonymous · Answer

f(4)=-12

D:...My teacher always made me do it using division....:'[ It was hard lol.

anonymous · Answer

Unfortunately, some high school teachers do not want their students to use any other methods that maybe they do not know.

ironically..in high school, teachers force you to use certain formulas only but students want to do other formulas, which are easier..in college students are free to use whichever formula they want but they stick to what the teachers "advise" them to use =))
