Lt ( quad frac{x^{2}-a x+b}{x-1}=5 ) ( vec{m} ) ( 15+frac{x(x-a)}{1}+1 ) Wr LHon'tal ( =lim _{x rightarrow 1} frac{2 x-9}{1}=5 ) ( therefore quad 2 - a = 5 quad Rightarrow 1 longdiv { a = - 3 } ) ". ( fleft(frac{x^{2}+3 x+b}{x-1}=5right. ) ( 9+b=-7 ) ( begin{aligned} Rightarrow quad frac{x^{2}-x+4 x+b}{x-1} & Rightarrow x+frac{4 n+1}{n-1} &=b+4=end{aligned} )
