The polynomial () (+) is a cubic polynomial: after multiplying out and collecting terms of the same degree, it becomes + +, with highest exponent 3.. The polynomial (+ +) + (+ + +) is a quintic polynomial: upon combining like terms, the two terms of degree 8 cancel, leaving + + + +, with highest exponent 5.
In mathematics, a monomial is, roughly speaking, a polynomial which has only one term.Two definitions of a monomial may be encountered: A monomial, also called a power product or primitive monomial, [1] is a product of powers of variables with nonnegative integer exponents, or, in other words, a product of variables, possibly with repetitions. [2]
In this case, a polynomial may be said to be monic, if it has 1 as its leading coefficient (for the monomial order). For every definition, a product of monic polynomials is monic, and, if the coefficients belong to a field , every polynomial is associated to exactly one monic polynomial.
The discriminant Δ of the cubic is the square of = () (), where a is the leading coefficient of the cubic, and r 1, r 2 and r 3 are the three roots of the cubic. As Δ {\displaystyle {\sqrt {\Delta }}} changes of sign if two roots are exchanged, Δ {\displaystyle {\sqrt {\Delta }}} is fixed by the Galois group only if the Galois group is A 3 .
Image for 9-points theorem, special case, when both C 1 and C 2 are unions of 3 lines. In mathematics, the Cayley–Bacharach theorem is a statement about cubic curves (plane curves of degree three) in the projective plane P 2.

The monomial X 1 X 2 gives the invariant 2(X 1 X 2 + X 3 X 4). It is not a resolvent invariant for G, because being invariant by (12), it is in fact a resolvent invariant for the larger dihedral subgroup D 4: (12), (1324) , and is used to define the resolvent cubic of the quartic equation.
The Lucas cubic is the locus of a point X such that the cevian triangle of X is the pedal triangle of some point; the point lies on the Darboux cubic. The Lucas cubic passes through the centroid, orthocenter, Gergonne point, Nagel point, de Longchamps point, other triangle centers, the vertices of the anticomplementary triangle, and the foci of ...
