$\huge\color{blue}{ \colorbox{pink}{\colorbox{white} {Solution}}}$

The equation can be simplified as

= x³ + x² – 4x² – 4x – 5x – 5

= x²(x + 1) – 4x (x + 1) – 5(x + 1)

= (x + 1)(x² – 4x – 5)

= (x + 1)(x² -5x + x – 5)

= (x + 1)(x – 5)(x + 1)

Hence, (x +1), (x -5) and (x +1) are the factors of given polynomial .

Answer 2

Answer:

The equation can be simplified as

= x³ + x² – 4x² – 4x – 5x – 5

= x²(x + 1) – 4x (x + 1) – 5(x + 1)

= (x + 1)(x² – 4x – 5)

= (x + 1)(x² -5x + x – 5)

= (x + 1)(x – 5)(x + 1)

Hence, (x +1), (x -5) and (x +1) are the factors of give polynomial
