We classify all cubic systems possessing the maximum number of invariant straight lines (real or complex) taking into account their multiplicities. We prove that there are exactly 23 topological ...

Statement and proof of the Factor Theorem. Factorisation of, ax2+bx+c, a is not equal to 0, where a,b, c are real numbers, and of cubic polynomials using the Factor Theorem. Recall of algebraic ...
