Answer:


\text{The solution set is }\{(-1)/(4), (1)/(2)\}

Explanation:

Given the equation


8x^2-2x=1

we have to find the solution of above equation.

Expression:
8x^2-2x=1


8x^2-2x-1=0


8x^2-4x+2x-1=0


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


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


x=(-1)/(4), (1)/(2)


\text{The solution set is }\{(-1)/(4), (1)/(2)\}

Option B is correct
