derivative of

f (x) = x^{2} - 2 x + 3

\frac{x - 1}{x ^{2} - 2 x + 3}

Solution steps

\frac{d}{d x} (x^{2} - 2 x + 3)

Apply the chain rule:

\frac{1}{2 x ^{2} - 2 x + 3} \frac{d}{d x} (x^{2} - 2 x + 3)

= \frac{1}{2 x ^{2} - 2 x + 3} \frac{d}{d x} (x^{2} - 2 x + 3)

\frac{d}{d x} (x^{2} - 2 x + 3) = 2 x - 2

= \frac{1}{2 x ^{2} - 2 x + 3} (2 x - 2)

Simplify

\frac{1}{2 x ^{2} - 2 x + 3} (2 x - 2) : \frac{x - 1}{x ^{2} - 2 x + 3}

= \frac{x - 1}{x ^{2} - 2 x + 3}
