Answer:

x = -7, x = 9

Step-by-step explanation:

We presume your equation is ...

x² -2x -63 = 0

Factors of -63 that have a sum of -2 are -9 and +7. Then the factored equation is ...

(x -9)(x +7) = 0

Solutions make the factors zero.

x -9 = 0 ⇒ x = 9

x +7 = 0 ⇒ x = -7

The solutions to the quadratic equation are x = -7 and x = 9.
