x² - 3x - 2x +6 = x(x - 3) - 2(x - 3)

                  =(x - 3)(x - 2)

suy ra ta tìm được nghiệm của pt là x= 3 hoặc x=2

=>  \(4.S=1+\frac{2}{4}+\frac{3}{4^2}+\frac{4}{4^3}+...+\frac{2014}{4^{2013}}\)

=> 4.S - S = \(\left(1+\frac{2}{4}+\frac{3}{4^2}+\frac{4}{4^3}+...+\frac{2014}{4^{2013}}\right)-\left(\frac{1}{4}+\frac{2}{4^2}+\frac{3}{4^3}+...+\frac{2014}{4^{2014}}\right)\)

=> 3.S = \(=1+\left(\frac{2}{4}-\frac{1}{4}\right)+\left(\frac{3}{4^2}-\frac{2}{4^2}\right)+\left(\frac{4}{4^3}-\frac{3}{4^3}\right)+...+\left(\frac{2014}{4^{2013}}-\frac{2013}{4^{2013}}\right)-\frac{2014}{4^{2014}}\)

=> 3.S =  \(1+\frac{1}{4}+\frac{1}{4^2}+...+\frac{1}{4^{2013}}-\frac{2014}{4^{2014}}\)

Tính A= \(1+\frac{1}{4}+\frac{1}{4^2}+...+\frac{1}{4^{2013}}\)

=> \(4.A=4+1+\frac{1}{4}+\frac{1}{4^2}+...+\frac{1}{4^{2012}}\)

=> 4.A - A = \(4-\frac{1}{4^{2013}}\)=> A= \(\frac{4}{3}-\frac{1}{3.4^{2013}}\)
