Hello, I'm not quite sure if im doing this right: Is: 4x+20: 4(-5 + x) factorized? and also for: 2y+16 2(8 + y) thanks

There should not be a "-" before the 5. and also for: 2y+16 2(8 + y) thanks Correct- although there is no reason in either this one or the first problem to reverse the order ("8+ y" instead of "y+ 8"), that's not a mathematical difference.
