Answer from: ctyrector

-k (k+1) (k+2)

Step-by-step explanation:

-2k - k³ - 3k² (factor-k out)

-k (2 + k² + 3k) (rearrange to standard quadratic form)

-k (k² + 3k + 2) (factor expression inside parentheses using your favorite method)

-k (k+1) (k+2)

Answer from: MysteryDove12

Option c.

Step-by-step explanation:

The given expression is

-2k-k^3-3k^2

We need to find the factor form of the given expression.

Taking out HCF.

-k(2+k^2+3k)

Arrange the terms according to there degree.

-k(k^2+3k+2)

Splitting the middle terms we get

-k(k^2+2k+k+2)

-k((k^2+2k)+(k+2))

-k(k(k+2)+(k+2))

-k(k+1)(k+2)

The factor form of given expression is -k(k+1)(k+2). Therefore, the correct option is c.

Answer from: amulets5239

-k (k + 2) (k + 1)

Step-by-step explanation:

Factor the following:

-k^3 - 3 k^2 - 2 k

Factor -k out of -k^3 - 3 k^2 - 2 k:

-k (k^2 + 3 k + 2)

The factors of 2 that sum to 3 are 2 and 1. So, k^2 + 3 k + 2 = (k + 2) (k + 1):

-k (k + 2) (k + 1)

Answer from: franklinkaylieg3873

-k(k + 2)(k + 1)

Step-by-step explanation:

-k is a common factor here.  Factoring -k out, we get:

-k(2 + k^2 + 3k), or (after writing the quadratic in standard form)

-k(k^2 + 3k + 2) = -k(k + 2)(k + 1)
