Quand vous développez le produit de deux binômes, vous obtenez un trinôme de la forme : a x 2 + b x+ c, a, b et c étant des nombres réels. Quand on fait l'opération inverse, passer du trinôme au produit de binômes, on dit qu'on factorise. Pour plus de clarté, il faut classer les termes d'un trinôme par ordre de puissance décroissante.

To figure out how we would factor a trinomial of the form x 2 + b x + c, x 2 + b x + c, such as x 2 + 5 x + 6 x 2 + 5 x + 6 and factor it to (x + 2) (x + 3), (x + 2) (x + 3), let’s start with two general binomials of the form (x + m) (x + m) and (x + n).

Factor trinomials using the AC method. Factoring Trinomials of the Form x2 + bx + c. Some trinomials of the form x2 + bx + c can be factored as a product of binomials. If a trinomial of this type factors, then we have: x2 + bx + c = (x + m)(x + n) = x2 + nx + mx + mn = x2 + (n + m)x + mn. This gives us. b = n + m and c = mn.
