Answer:

  -2

Step-by-step explanation:

The first two terms have a common factor of x. Taking that out gives ...

  (x² +5x -2) ÷ (x +5)

  = (x(x +5) -2) ÷ (x +5)

  = x -2/(x +5)

The remainder is -2.

_____

The remainder can also be found by evaluating (x² +5x -2) for x = -5:

  (-5)² +5(-5) -2 = 25 -25 -2 = -2

The remainder is -2.
