Answer:-
A cubic equation is a polynomial equation of degree three, typically written as ax³ + bx² + cx + d = 0, where a ≠ 0. Solving cubic equations can be done using various methods, including factoring (if possible), synthetic division, or the cubic formula. The Rational Root Theorem helps identify possible rational roots to test. When factoring isn't straightforward, Cardano's method (cubic formula) can be used, though it's more complex. In many cases, graphing calculators or software can assist in finding the roots. Cubic equations can have one real root and two complex roots, or all three roots real.
