We have no book and I am trying to go through example problems. I probably need to get a book and learn this all over again. 50 years old no and not done this since 20 years old.

2xsquared-8x+2=0

(2x-2)(1x-1) gets me 4x in the middle when I multiply it through.

Is this the right way to approach this, did I do something silly?
