Abstract
The Cardano method that is evaluated in numerical analysis in general covers equations having complex coefficients. But major numerical computations of practical programs contain equations having real coefficients, and there is an increase in the requirement for high speed computation of programs containing such equations. In this paper, we propose a new method for improving the approximation of numerical solutions and for speeding up the computation by applying a deflation of degree to the Cardano method and modifying it to handle real coefficients.
