Explanation:
#"the equation of a parabola in "color(blue)"standard form"# is.
#•color(white)(x)y=ax^2+bx+c color(white)(x);a!=0#
#"expand the factor "(8x-1)^2" using FOIL"#
#y=1/2(64x^2-16x+1)-3/2#
#"distribute the bracket"#
#y=32x^2-8x+1/2-3/2#
#color(white)(y)=32x^2-8x-1larrcolor(red)"in standard form"#
