Factor the following equation to solve for \( x \):

\[ x^{2} - 8x - 20 = 0 \]

x² - 8x - 20 = 0
Factor the left side:
(x + 2) (x - 10) = 0
That's a true statement if (x = -2) or if (x= 10), so those are your solutions.
x = -2 x = 10
By the way ... you don't factor an equation. You can only factor an expression.

To factor the equation x 2 − 8 x − 20 = 0 , we rewrite it as ( x − 10 ) ( x + 2 ) = 0 . The solutions are x = 10 and x = − 2 .
