WebOct 29, 2015 · Finding solutions to an equation is equivalent to finding roots of a function. Suppose you wanted to solve the equation x 3 = 6 − 7 x 2. That means you want to find all numbers x such that x 3 = 6 − 7 x 2. Of course these are the exact same numbers which make x 3 + 7 x 2 − 6 = 0 which are exactly the roots of the function F ( x) = x 3 + 7 x 2 − 6. WebFor the cubic, we manage to exploit some symmetries of the problem to reduce it to a quadratic equation. The quartic has 4 roots, and 4!=24 permutations, but we still manage to reduce it to a cubic equation by exploiting more symmetries.
