" (ii) "x+(4)/(x)=-4,x!=0

Solve the following equation: x+(4)/(x)=-4, x ne 0

Evaluate the left-and right-hand limits of the function f(x)={(|x-4|)/(x-4),x!=4, 0,x=4 ,at x=4

Evaluate the left-and right-hand limits of the function f(x)={(|x-4|)/(x-4),x!=4 0,x=4a tx=4

Evaluate the left-and right-hand limits of the function f(x)={(|x-4|)/(x-4),x!=4 0,x=4a tx=4

Evaluate the left-and right-hand limits of the function f(x)={(|x-4|)/(x-4),x=4, 0,x=4

(x)/(x-1)+(x-1)/(x)=4(1)/(4),x!=0,1

Solve for x,6sqrt((x)/(x+4))-2sqrt((x+4)/(x))=11,x!=0,-4

((x+4)/(x-4))^2-5((x+4)/(x-4))+6=0,(x!=4)
