In basic mathematics, it is used as a formula to evaluate the difference of cubes of two quantities. It is also used as a formula to write the difference of two quantities in cube form as a product of two factors. Learn more Proofs WebWe show how identity (1) can be used to \solve" a particular cubic equation, and then generalize to allcasus irreducibiliscubics. 1.3.1 A Special Equation We solve the equation 4x3−3x=−1 2 Look for a solution of the form x=cos .Then4x3−3x=cos3 , so by identity (1) we are looking at the equation cos3 =−1=2. Recall that cos120 =−1=2. ryerson photography
