Trying to plot the function 7*x^2+22*xy+7*y^2+14*xz*sqrt(3)+14*yz*sqrt(3)-5*z^2 = 180, I tried using implicitplot3d to plot it, with ranges I'm quite certain should contain the surface but for whatever reason all I get is a blank plot with no graphics. Here's my input:

 

Loading plots

with(plots);
[animate, animate3d, animatecurve, arrow, changecoords,

complexplot, complexplot3d, conformal, conformal3d,

contourplot, contourplot3d, coordplot, coordplot3d,

densityplot, display, dualaxisplot, fieldplot, fieldplot3d,

gradplot, gradplot3d, implicitplot, implicitplot3d, inequal,

loglogplot, logplot, matrixplot, multiple, odeplot, pareto,

polygonplot3d, polyhedra_supported, polyhedraplot, rootlocus,

semilogplot, setcolors, setoptions, setoptions3d, spacecurve,

sparsematrixplot, surfdata, textplot, textplot3d, tubeplot]
implicitplot3d(7*x^2+22*xy+7*y^2+14*xz*sqrt(3)+14*yz*sqrt(3)-5*z^2 = 180, x = -50 .. 50, y = -50 .. 50, z = -50 .. 50, axes = normal);

 

Not sure what I'm doing wrong exactly.
