not quite. try getting the x's on the same side first, then you should be able to factor it (I'm assuming you're working on factoring.

dumbcow · Answer

last step is wrong.

i would factor out the a on left side first

anonymous · Answer

What is factoring? I dont recall seeing that in one of the videos.

turingtest · Answer

If you can't factor this is gonna be tricky, you should try to look up something on it, see if you can understand the idea. It'll be a good exercise on how to research a math concept. Here's a start: http://www.purplemath.com/modules/simpfact.htm try to find Khan videos on it too.

Isnt it better for me to go through the khan videos systematically?

turingtest · Answer

Where did you get this problem?

anonymous · Answer

A guy gave it too me here on OS, why?

turingtest · Answer

Well then he didn't know that you had not yet studied factoring, so ignore it I guess and come back to it when you get there in khan. It's definitely a whole idea by itself, you will have to devote a fair amount of attention to it at first. Gets easy soon though :)
