Answer:

x = -5, 7

Explanation:

Step 1: Write equation

x² - 2x - 35 = 0

Step 2: Solve for x

Factor: (x - 7)(x + 5) = 0

Find roots: x = -5, 7

Step 3: Check

Plug in x to verify if it's a solution.

(-5)² - 2(-5) - 35 = 0

25 + 10 - 35 = 0

35 - 35 = 0

0 = 0

7² - 2(7) - 35 = 0

49 - 14 - 35 = 0

35 - 35 = 0

0 = 0
