Answer:

f(x)=(x+1)(x+2)(x−4)

Step-by-step explanation:

f(x) = x^3 - x^2 - 10x - 8.

We find out that

f(-1) = -1 -1 + 10 - 8 = 0,

then, one factor is (x + 1).

After division --> 

f(x)=(x+1)(x2−2x−8)

The trinomial in parentheses can be factored.

Find 2 numbers knowing sum (-2) and product (-8). 

They are (2) and (-4)

(x2−2x−8)=(x+2)(x−4)

f(x)=(x+1)(x+2)(x−4)

Answer:

(x-2) (3x+4)

Step-by-step explanation:

3x 2−10x+8

−6×−4=24...the product of the coefficient of the first and the last term

−6+−4=−10..the split for the middle term

Now, splitting the middle term we get

=3x 2 −6x−4x+8

=3x(x−2)−4(x−2)

=(x−2)(3x+4)

hope help uh ❤
