I really need help asap show all work​

Answer 1

Note: Consider we need to find the factor form of the given expression by taking out the GCF.

Given:

The expression is:

`-42k^3+24k^4+12k^5`

To find:

The factor form of the given expression.

Solution:

We have,

`-42k^3+24k^4+12k^5`

It can be written as:

`=6k^3(-7)+6k^3(4k)+6k^3(2k^2)`

Taking out the greatest common factor (GCF), we get

`=6k^3(-7+4k+2k^2)`

Therefore, the factor form of the given expression is
`6k^3(-7+4k+2k^2)`.
