Question

Find the zeros of the function
g(x) = 2x^4+ 2x^3− 6x^2− 2x + 4 .

Answer 1

\[x-1\] is a factor beause \[f(1)=0\] and also if we try \[x=-1\]
it works so we have two other factors to get
x=1 twice
x=-1
x=-2

Answer 2

Hi deejay :)

set g(x)=0
and solve it for x.

You will get 4 answers as x has maximum 4 exponent

Answer 3

those were the only 3 i knew how to get. . but my answer was wrong.

Answer 4

ok the equation is
\[y=2(x-1)(x-1)(x+1)(x+2)\]
roots \[x=-2,x=-1,x=1\]

Answer 5

since x=1 appears twice
