Hello There!

Let's expand all the options to see which one is correct:

(x + 5)(x - 1)
==> [tex] x^{2} + 4x - 5[/tex]

(x +5)(x+1)
==> [tex] x^{2} + 6x + 5[/tex]

(x - 5)(x - 1)
==> [tex] x^{2} - 6x + 5[/tex]

(x - 5)(x + 1)
==> [tex] x^{2} - 4x - 5[/tex]

Therefore, it is option D.

Hope This Helps You!
Good Luck :)
