(x + 1)(x + 4)


-(x + 1)(x + 4)


-(x + 1)(x - 4)

Answer 1

The answer to your question is -(x + 1)(x + 4)

Explanation:

Data

Polynomial -x² - 5x - 4

Process

1.- Factorize the sign

-(x² + 5x + 4)

2.- Factorize a polynomial of the form x² + bc + c

-(x + 1)(x + 4)

3.- It is not possible to continue factoring so the answer is

-(x + 1)(x + 4)
