-------------------------------\\\\
f(x)= \cfrac{1}{x} \qquad 
\begin{cases}
x_1=2\\

\end{cases}\implies \cfrac{f(b)-f(2)}{b-2}=-\cfrac{1}{10}
\\\\\\
\cfrac{\frac{1}{b}-\frac{1}{2}}{b-2}=-\cfrac{1}{10}\implies 
\cfrac{\frac{2-b}{2b}}{b-2}=-\cfrac{1}{10}\implies \cfrac{2-b}{2b}=-\cfrac{b-2}{10}

$\bf \cfrac{2-b}{2b}=\cfrac{2-b}{10}\implies 20-10b=4b-2b^2\impliedby cross-multiplying
\\\\\\
2b^2-4b-10b+20=0\implies 2b^2-14b+20=0

b^2-7b+10=0\implies 
(b-2)(b-5)=0\implies b=

Let's find.

$\\ \rm\Rrightarrow (-2x^3+x-5)(x^3-3x+4)$

$\\ \rm\Rrightarrow x^3(-2x^3+x-5)-3x(-2x^3+x-5)+4(-2x^3+x-5)$

$\\ \rm\Rrightarrow -2x^6+x^4-5x^3+6x^4-3x^2+15x-8x^3+4x-20$

$\\ \rm\Rrightarrow -2x^6+7x^4-13x^3-3x^2+19x-20$

Yes

It's because multiplication law states that ab=ba
