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.
last step is wrong.
i would factor out the a on left side first
What is factoring? I dont recall seeing that in one of the videos.
Not the answer you are looking for? Search for more explanations.
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:
try to find Khan videos on it too.
Isnt it better for me to go through the khan videos systematically?
Where did you get this problem?
A guy gave it too me here on OS, why?
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 :)
Ok, im looking forward to having a good understanding of these things!
