Rational root theorem are found, they can be factored out of the polynomial, resulting in a polynomial of lower degree whose roots are also roots of the original polynomial. The general cubic equation with integer coefficients has three solutions in the complex plane. If it is found by the rational root test that there are no rational solutions, then the only way to express the solutions algebraically is to use cube roots. But if the test finds three rational solutions, then the cube roots are avoided. And if precisely one rational solution "r" is found to exist, then ("x" – "r") can be
Professor's Cube inspection), set by Stanley Chapel of the United States on 27 July 2018 at CubingUSA Nationals 2018. A Filipino TV series from ABS-CBN Entertainment named "Little Big Shots", shows a 10-year old cuber named Franco, who solved a Professor's Cube in 1:47.12 minutes Professor's Cube The Professor's Cube is a combination puzzle, a 5×5×5 version of the Rubik's Cube. It has qualities in common with both the original 3×3×3 Rubik's Cube and the 4×4×4 Rubik's Revenge, and knowing how to solve either can help when working on the 5×5×5 cube. Early versions of the 5×5×5 cube sold at Barnes &
