Question

*HELP!** Factor this polynomial completely over the set of complex roots.
f(x)=x^3-x^2-4x+4

Answer 1

see this

\( x^3-x^2-4x+4=x^2(x-1)-4(x-1) \)

Answer 2

How many zeros?

Answer 3

2 zeros

Answer 4

\( x^3-x^2-4x+4=x^2(x-1)-4(x-1)=(x-1)(x^2-4)=(x-1)(x-2)(x+2) \)

Answer 5

opps 3 zeros

Answer 6

if @experimentX taught me right yesterday.

Answer 7

oh ... that was just clearing up confusion ... lol

Answer 8

Thanks!!

Answer 9
