A = 1+2+2²+2³+...+2⁶³ 

=> 2A = 2+2²+2³+...+2⁶³+2⁶⁴

=> 2A - A = 2⁶⁴ - 1

Vậy A = 2⁶⁴ - 1

\(=\left(x^3+1\right)-12x\left(x+1\right)\)

= \(\left(x+1\right)\left(x^2-x+1\right)-12x\left(x+1\right)\)

= \(\left(x+1\right)\left(x^2-13x+1\right)\)

= \(\left(x+1\right)\left(x-\frac{13+\sqrt{165}}{2}\right)\left(x-\frac{13-\sqrt{165}}{2}\right)\)
