x=10,x=-1
Is this correct. I am not sure which method I used and why I would use this particular method over another and need some help with that.Thanks (Sorry this is so long I don't like to do this because of that, but I wanted you to see my work on this one.)

You've got it. Not the route I would take, but it gets you to the answer nonetheless. I would've factored the left side to easily solve for x.
What 2 numbers multiply to -10 and add to -9. They are -10 and 1
Factor the left side
Set each factor equal to 0
There's one answer
There's the other answer
So x=-1 or x=10
But if it works for you then you should stick with it.
