What the hell is wrong with this, C3 Maths thanks.

How are these the same, because x^2 -2x + 3 simplified to (x-1)^2

So surely it would be (x-1)^2 + 2 / (x-1)^2

which is just 2. I dont get it.. Problem attached below.

Not quite. If it were

(x-1)^2*2

on the numerator, you'd be right.

\frac{(x-1)^2 + 2}{(x-1)^2}

= \frac{(x-1)^2}{(x-1)^2} + \frac{2}{(x-1)^2}

= 1 + \frac{2}{(x-1)^2}
