Question 652546
{{{(1/(x + h)^2 - 1/x^2)/H}}}


{{{((1x^2 - 1(x + h)^2)/(x^2(x + h)^2))/H}}}


{{{(1x^2 - 1x^2+2hx + h^2)/(Hx^2(x + h)^2))}}}


{{{(cross(1x^2) - cross(1x^2)+2hx + h^2)/(Hx^2(x + h)^2))}}}


{{{(2hx + h^2)/(Hx^2(x + h)^2))}}}


{{{h(2x + h)/(Hx^2(x + h)^2))}}}


{{{h(2x + h)/(Hx^2(x + h)(x + h)))}}}
