The answer is x=9
Explanation: x + 16 = x^2 - 8x +16
x = x^2 - 8x
9x - x^2 = 0
X x (9-x) = 0

Like... 276 divided by 4... My 4th grade teacher is teaching us a way of long division, here are the steps. Divide, Multiply, Subtract Bring down, Repeat... Here is the example. 4 to 2, I cant make 2 with 4. 4 is too big, then i go to 27. the closest i can get is 6x4 to make 24. then on top i put 6, then i multiply 4x6 and put 24 down below 27. Then I subtract then bring down the 6. Next step, repeat. Do 4 divided by 3, the closest i can get to 4 is by doing 3x1 so i put the 1 up by the 6 then multiply 1x4. Which is 4, then i bring it down then subtract 36 - 4. You get 61 with a remainder of 4. :) Hope that helped and isn't too confusing!
