Answer 1

what's the question?

Answer 2

it just says solve.

Answer 3

can anyone help??

Answer 4

(5x/4)-(3/x)=(1/4)
<=> ((5x^2)-12)/4x=(1/4)
<=>[((5x^2)-12)/4x]-(1/4)=0
<=>[((5x^2)-12)*4-4x/4x]=0
<=>((20x^2)-48-4x)/4x=0
<=>(5x^2)-x-12=0
delta=sqrt(240)
x1=1-sqrt(240)/10
x2=1+sqrt(240)/10
S={1-sqrt(240)/10,1+sqrt(240)/10}
