Answer:


x = ( 3\pm \sqrt7)/(2)

Explanation:

The given equation to us ,


\implies 6x = 2x^2 + 1

So we will use quadratic formula and solve out for x .


\implies 6x = 2x^2 + 1 \\\\\implies 2x^2 -6x + 1 = 0 \\\\\implies x = (-b\pm √( b^2-4ac))/(2a) \\\\\implies x = ( 6 \pm √( (-6)^2-4(2)(1) ))/(2(2)) \\\\\implies x = ( 6 \pm √( 36 - 8 ))/(4) \\\\\implies x = ( 6 \pm √( 28))/(4) \\\\\implies \boxed{\boxed{ x = ( 3\pm \sqrt7)/(2) }}
