Here's the question you clicked on:

express x² + 10x + 32 in the form (x + a)² + b where a, b = N
\[a, b \in \mathbb{N}\]
I'm not sure but I'll try - I think it might go like this.
(x|dw:1316456509340:dw|
whered u get ''25'' :o?
If you have any questions by all means ask - I'm not completely sure about this
When converting from x^2+10x+32 to the form of (x+#)^2 + # you have to take the middle number which in this case is 10. You divide it by 2, which is 5, then you square that answer (5)^2
ur original form was standard form, and the middle number is called "b" - so the rule is to change from standard form to that new form you need to do this (b/2)^2
That's where the 25 comes from - once you have the 25 you can actually convert the form to that new form.
think i get it now, thx man :P
Do you want me to draw out the answer in better detail, just to be sure you get it?
na its ok, i know how to do the sum, but was stuck with the ''10''
