`1/((x-2)(x-4))+1/((x-4)(x-6))+1/((x-6)(x-8))+1/3=0`

Solve: 1/((x-1)(x-2))+1/((x-2)(x-3))+1/((x-3)(x-4))=1/6[x!=1,2,3,4]

Solvef or x,(1)/((x-1)(x-2))+(1)/((x-2)(x-3))+(1)/((x-3)(x-4))=(1)/(6)

Solve for x : (1)/((x-1)(x-2))+(1)/((x-2)(x-3))+(1)/((x-3)(x-4))=(1)/(6)

((x-1)(x+1)(x+4)(x+6))/(7x^2+8x+4)>0

((x-1)(x+1)(x+4)(x+6))/(7x^(2)+8x+4)>0

((x-1)(x+1)(x+4)(x+6))/(7x^2+8x+4)>0

(x+1)(x-3)(x+2)(x-4)+6=0

The coefficient of x^(8) in the expasnsion of (1+(x^(2))/(2!)+(x^(4))/(4!)+(x^(6))/(6!)+(x^(8))/(8!))^(2) is

(x^(2)+(1)/(x^(2)))-4(x+(1)/(x))+6
