Factor the polynomial: -x^3-4x^2-5x

-x(x^2 + 4x + 5).

Step-by-step explanation:

-x^3-4x^2-5x

First take out -x:

= -x(x^2 + 4x + 5)

It can't be factored any further.

given expression is

we have radical  

we need to select an option that has same radical

(a)  

this expression has cube root instead of square root . so it is not a like radical.

(b)

y is included inside the radical. so it is not a like radical.

(c)

this expression has cube root instead of square root . so it is not a like radical.

(d)

5 is inside the radical square root. so it is   a like radical.
