Which real numbers are zeros of the function? f(x)=2x3−x2−8x+4 select each correct answer. −2 −1 −12 0 12 1 2

Step-by-step explanation:

Given is a function in x as

We have to find the zeroes of the function

Since this is a cubic function this function has three zeroes.

Let us try to factorise this function by grouping two terms together.

=

Equate each factor to 0 to find zeroes as

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

correct answer is c. just did it
