## variables

Noun

- plural form of
*variable*

- This is of degree 8 in the coefficients, and degree 6 in the
**variables**, and, for the canonical form, has the expression -9m 6 (x 3 +y 3 +z 3) 2 - (2m +5m 4 +20m 7) (x3 +y3+z3)xyz - (15m 2 +78m 5 -12m 8) Passing on to the ternary quartic we find that the number of ground forms is apparently very great. - Hermite expresses the quintic in a forme-type in which the constants are invariants and the
**variables**linear covariants. - He proves, by means of the six linear partial differential equations satisfied by the concomitants, that, if any concomitant be expanded in powers of xi, x 2, x 3, the point
