While we wait for you to show some effort at solving this problem, let me make a point.danielp3 said:( Poster has been reminded to post school work-type questions in the Homework Help forums, and to show some work on the problem. )

A cubic equation is a polynomial equation of the form ax^3 + bx^2 + cx + d = 0, where a, b, c, and d are constants and x is the variable. It has a maximum of three solutions.
An equation is considered a cubic equation if the highest exponent of the variable is 3. For example, x^3 + 2x^2 + x - 5 = 0 is a cubic equation, while x^2 + 3x + 1 = 0 is not.
The general method for solving a cubic equation is by using the cubic formula, which is x = (-b ± √(b^2 - 4ac - 3a^2) / 2a. However, this method can be quite complex and time-consuming, so there are other methods such as factoring and using the rational roots theorem that are often used instead.
Yes, all cubic equations can be solved. However, some equations may have complex or irrational solutions, which may not be easily calculable.
One helpful tip is to first try to factor the equation to see if any solutions can be easily found. Another tip is to use the rational roots theorem to narrow down the possible solutions. It may also be useful to work with a graphing calculator or software to visualize the equation and its solutions.
