DISEQUAZIONI FATTORIZZATE - ESERCIZI (1)

Discover the mathematics courses https://andreailmatematico.it/corsi-m... Factored inequalities are inequalities where the product of elements in a given unknown is inequalified to zero. The form they take is: f1(x) * f2(x) *...*fn(x)≻0 Where on the left side are the factors f1(x), f2(x), ..., fn(x), while on the right side is zero. Polynomial factorization is often used to achieve this form. The first step in solving factored inequalities is to study the signs of the factors, which consists of studying the factors greater than (or possibly equal to) zero: f1(x)≻0 f2(x)≻0 … fn(x)≻0 Next, we construct a sign table, plotting all the particular solutions on the number line, which are the particular values ​​of x that cancel the factors. Then we add positive and negative signs depending on where the factors are positive or negative. Finally, multiply the signs of each region and identify the positive region as the solution, or, if necessary, the negative region if the initial inequality is less than zero.
