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
C-Cube Umesh Padval was brought in to run C-Cube Semiconductor in 1998. During the late 1990s, C-Cube was unable to repeat its runaway hits seen earlier in the decade. The company sold its DiviCom division to Harmonic Lightwaves in May, 2000 for nearly $1.7 billion. C-Cube Semiconductor (Nasdaq CUBED) was eventually sold to competitor LSI Logic in March 2001 in a stock transaction worth $878 million. LSI sold off the consumer products business (including what was C-Cube) to Magnum Semiconductor in 2007. C-Cube C-Cube Microsystems was an early company in video compression technology as well as the implementation of that technology
