(x^(2)-(x+1)(x+2))/(5x+1)=6

If y=x+(1)/(x),xne0 , then the equation (x^(2)-3x+1)(x^(2)-5x+1)=6x^2 reduces to

If y= x+(1)/(x), x ne 0 , then the equation (x^(2)-3x+1)(x^(2)-5x+1)=6x reduces to

Solve (x^(2)+(1)/(x^(2)))-5(x+(1)/(x))+6=0," when "x ne0

(x^(2)+1)/(x^(2)-5x+6)

If (x^(2)-5x+6)/(x^(2)-x+1) is positive, then :

Solve the inequality: (x^(2)-1)/(x^(2)+1)+x^(2)-5x+6<0

Let f(x) = {(x^(4)-5x^(2)+4)/(|(x-1)(x-2)|) x ne 1,2),(6, x=1), (12, x =2):} . Then, f(x) is continuous on the set
