X^2-2=x
x^2-2+x=0
x^2+x-2=0
(x+2)(x-1)=0
Therefore, x+2=0 or x-1=0
Hence, x=-2 or x=1
Solutions= -2 or 1

Okay , wheres the questions at tho...?
Because y varies inversely as x, therefore
where k = constant.
When x = 6, y = 2.5. Ther efore
Cross multiply.
k = 6 x 2.5 = 15
The equation is
When x = 4, obtain
