Factor the polynomial: – x3 - 4x2 - 5x

Alinara [238K]

Answer:

$-x3-4x2-5x=-x(x^2+4x+5)$

Step-by-step explanation:

we are given the polynomial as

$-x3-4x2-5x$

here we can see that the GCF of $-x^3$ , $-4x^2$ and $-5x$ is

$-x$

Hence we take it outside the bracket

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

The polynomial within the bracket $x^2+4x+5$ can not be factorized further , hence this would be our final answer.
