Question

I need to know the answer to this very important thank you

Answer 1

we have

f(x)=2x^3+4x^2-2x-4

using a graphing tool

Find out the zeros of the given function

see the attached figure

the zeros are

-2, -1 and 1

that means

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

therefore

the answer is the option B
