Answer:

#x= (2+-sqrt((-2)^2-4(2)(-1)))/(2(2)#

Explanation:

The standard form of a quadratic equation is
#color(white)("XXX")color(red)(a)^2+color(blue)(b)x+color(green)(c)=0#
and for this standard form the quadratic formula is
#color(white)("XXX")x=(-color(blue)(b)+-sqrt(color(blue)(b)^2-4color(red)(a)color(green)(c)))/(2color(red)(a))#

#2x^2-2x=1#
can be converted into the standard form as
#color(white)("XXX")color(red)((2))x^2+color(blue)((-2))x+color(green)((-1))=0#
