1. ## Factoring

I've had trouble factoring things like this since I was a freshman. Could someone explain in detail how to factor this.
$2x^2-8x+8$

first rule of factoring ... pull out any factors each term has in common.

$2(x^2 - 4x + 4)$

can you factor the quadratic in ( ... ) now ?

btw, it's a perfect square
