X2-16 2x-8

It looks like you want to simplify or factor the expression \( x^2 - 16 \) and \( 2x - 8 \). Let's go through both expressions.

1. Factoring \( x^2 - 16 \):

   • This expression is a difference of squares, which can be factored as follows: \[ x^2 - 16 = (x - 4)(x + 4) \]

2. Factoring \( 2x - 8 \):

   • We can factor out the common factor from the expression: \[ 2x - 8 = 2(x - 4) \]
