Answer:

x = -5, 7

Step-by-step explanation:

Step 1: Write equation

x² - 2x - 35 = 0

Step 2: Solve for <em>x</em>

<u>Factor:</u> (x - 7)(x + 5) = 0

<u>Find roots:</u> x = -5, 7

Step 3: Check

<em>Plug in x to verify if it's a solution.</em>

(-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
