Explanation:
#"the equation of a parabola in "color(blue)"standard form"# is.
#color(red)(bar(ul(|color(white)(2/2)color(black)(y=ax^2+bx+c ; a!=0)color(white)(2/2)|)))#
#"expand " (x-1)^2" using FOIL"#
#y=4(x^2-2x+1)+5#
#color(white)(y)=4x^2-8x+4+5#
#color(white)(y)=4x^2-8x+9larrcolor(red)" in standard form"#
