Answer:

$(x+1)(5x-4)(x-2)$

Step-by-step explanation:

We know that (x+1) is a factor, so we can use synthetic division to factor it out of $5x^3-9x^2-6x+8$ .

Once factored, we get $(x+1)(5x^2-14x+8)$

Now all we need to do is factor $(5x^2-14x+8)$

$(5x^2-14x+8)=(5x-4)(x-2)$

This gives us the answer $(x+1)(5x-4)(x-2)$ .

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.

Instead of k, k+1, k+2, you should use k, k+2, k+4 with the constraint that k is even (i.e. if you return an odd integer for k, or a non-integer, then return no solution).

k + (k+2) + (k+4) = 4k

3k + 6 = 4k
k = 6

Indeed, 6+8+10 = 4*6.
