using sym I ended up with the following polynomial in y and x with terms x^2, x^4, x^2, y^4

(4*R^3*r^2*y^2 + R^3*y^4 + 4*R^2*r^3*x^2 + 2*R*r^2*x^2*y^2 + r^3*x^4)/(8*R^3*r^3)

I would like to divide the expression by the denominator 8*R^3*r^3, so for example the 1st term would say appear as y^2/(2*r)

Anyone know how to do this?

expr = str2sym('(4*R^3*r^2*y^2 + R^3*y^4 + 4*R^2*r^3*x^2 + 2*R*r^2*x^2*y^2 + r^3*x^4)/(8*R^3*r^3)')

expr =

expand(expr)

ans =
