Step-by-step explanation:
8x-2=3/x
multiple both side by x
we get:-
8x^2+2x=3
8x^2+2x-3=0
factorising
8x^2 -4x+6x+3=0
-4x(2x+1)+3(2x+1)=0
(2x+1)(-4x+3)=0
2x+1=0 -4x+3=0
2x=-1 -4x=-3
x=-1/2 x=3/4

Step-by-step explanation:
8x-2=3/x
=> 8x-2-3/x=0
=>8x²-2x-3=0
=>8x²-6x+4x-3=0
=>2x(4x-3)+1(4x-3)=0
=>(4x-3)(2x+1)=0
Either
4x-3=0 =>4x=3=>x=3/4
Or
2x+1=0=>2x=-1=>x=-1/2
