Explanation:
"the standard form of a quadratic function is "the standard form of a quadratic function is
color(red)(bar(ul(|color(white)(2/2)color(black)(y=ax^2+bx+c;a!=0)color(white)(2/2)|)))
"expand " (x+2)^2" using FOIL method gives"
y=-(x^2+4x+4)-7
color(white)(y)=-x^2-4x-4-7
color(white)(y)=-x^2-4x-11larrcolor(red)" in standard form"
