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

\frac{2 x ^{2} - 4 x + 3}{x ^{2} - 2 x + 2}

Solution steps

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

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = x - 1, g = x^{2} - 2 x + 2

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

\frac{d}{d x} (x - 1) = 1

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

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

Simplify

1 \cdot x^{2} - 2 x + 2 + \frac{x - 1}{x ^{2} - 2 x + 2} (x - 1) : \frac{2 x ^{2} - 4 x + 3}{x ^{2} - 2 x + 2}

= \frac{2 x ^{2} - 4 x + 3}{x ^{2} - 2 x + 2}

x \to - 8 lim (ln (x + 8))

\frac{d}{d x} (x^{2} - 9 x + 25)

y^{^{'}} = - \frac{3 y}{t} - 2 - t^{- 4}

n = 0 \sum \infty \frac{e ^{n}}{3 ^{n}}

\int_{\frac{1}{3}}^{1} \frac{y + 4}{y ^{2} + 2 y} d y
