Answer:
step 1: move the -4 to the right: x^2 -2x = 4
step 2: add 1 to each side: x^2 -2x + 1 = 4 + 1
step 3: factor the left side and simplify the right side: (x-1)^2 = 5
step 4: take the square root of each side: x - 1 = sqr root of 5
step 5: move the 1 to the other side: 
and 
I think that's 2x but I'm not really sure.
I hope this helps.

This is pretty simple. :) Since you have 6 rolls of dimes with 50 dimes in each, you would just do 6*50 which equals 300. So Hayden has 300 dimes altogether. Hope this helps! :)
3x + 2y - 2x + y + 12 —> x + 3y + 12
4y + 3y + 3x - 6y - 10 -2 —> 3x + y - 12
12 - 3y - 2x + x + 2x —> x - 3y + 12
x + 3y + 2x - 3x + 7 + 5 —> 3y + 12
