The geometrical key, or The gate of equations unlock'd : a new discovery of the construction of all equations, howsoever affected, not exceeding the fourth degree; viz. of (linears, quadratics, cubics, biquadratics;) and the finding of all their roots, as well false, as true; without the use of mesolabe, trisection of angles; without reduction, depression, or any other previous preparation of equations, by a circle, and any (and that but one only) parabole
