x^(2)-x+(1)/(4)=0

The function f(x)=(2x^(2)-1)/(x^(4)),x>0 decreases in the interval

solve for x : (1) x^(2) + (1)/(x^(2))=(17)/(4) (2) (x+1)/(x)+(x)/(x+1)=(25)/(12) (3) x^(2)+(1)/(x^(2))+x+(1)/(x)-4=0

The function f(x)=(2x^(2)-1)/(x^(4)), x gt 0 , decreases in the interval …………. .

((x+3)(x^(2)-5x+6))/((x^(2)+x+1)(x-4))<=0

Set of values of x satisfying (x^(2)-4x+1)^(2)+(x^(2)-4x+1)-2<=0 , is

State with reasons whether the sets defined in each of the following cases are equal : P = { x : x" is an integer and "-2 le xle2},Q={x:x (x^2-1)(x^2-4)=0}.
