Answer:

(-2, 0) and (4, -6)

Explanation:

You want the ordered pair solutions to the system of equations ...

  • f(x) = x² -3x -10
  • f(x) = -x -2

Solution

We can set the f(x) equal, rewrite to standard form, then factor to find the solutions.

x² -3x -10 = -x -2

x² -2x -8 = 0 . . . . . . . add x+2

(x +2)(x -4) = 0 . . . . . . factor

The values of x that make the product zero are ...

x = -2, x = 4

The corresponding values of f(x) are ...

f(-2) = -(-2) -2 = 0

f(4) = -(4) -2 = -6

The ordered pair solutions are (-2, 0) and (4, -6).
