The father of the protagonist borrows money from the mafia, and as a guarantee promises to give his eldest daughter, a beautiful girl that he had brought with him to demonstrate... When the time came to return the money or give up the daughter, the father decides to hide with her eldest daughter, and the youngest to give as payment of the debt. Small clever - makes a deal with the boss: if she will return the debt of his father before he finds fugitives, he back off. And here begins the most interesting.

## Cubic - Cubic function - Netflix

In algebra, a cubic function is a function of the form

f ( x ) = a x 3 + b x 2 + c x + d {\displaystyle f(x)=ax^{3}+bx^{2}+cx+d}

in which a is nonzero. Setting f(x) = 0 produces a cubic equation of the form

a x 3 + b x 2 + c x + d = 0. {\displaystyle ax^{3}+bx^{2}+cx+d=0.\,}

The solutions of this equation are called roots of the polynomial f(x). If all of the coefficients a, b, c, and d of the cubic equation are real numbers, then it has at least one real root (this is true for all odd degree polynomials). All of the roots of the cubic equation can be found algebraically. (This is also true of quadratic (second degree) or quartic (fourth degree) equations, but not of higher-degree equations, by the Abel–Ruffini theorem.) The roots can also be found trigonometrically. Alternatively, numerical approximations of the roots can be found using root-finding algorithms such as Newton's method. The coefficients do not need to be complex numbers. Much of what is covered below is valid for coefficients of any field with characteristic 0 or greater than 3. The solutions of the cubic equation do not necessarily belong to the same field as the coefficients. For example, some cubic equations with rational coefficients have roots that are non-rational (and even non-real) complex numbers.

## Cubic - Solution with angle trisector - Netflix

A cubic equation with real coefficients can be solved geometrically using compass, straightedge, and an angle trisector if and only if it has three real roots.
