Nous pouvons diviser le moyen terme de cette expression pour la factoriser et ainsi trouver la solution.

Dans cette technique, si nous devons factoriser une expression comme  

a  

x  

2

+  

b  

x  

+  

c

, nous devons penser à 2 nombres tels que:

N  

1

⋅

N  

2

=

a

⋅

c

=

1

⋅

9

=

9

ET

N  

1

+

N  

2

=

b

=

6

Après avoir essayé quelques chiffres, nous obtenons  

N  

1

=

3

et  

N  

2

=

3

3  

⋅  

3  

=  

9

, et  

3  

+  

3  

=  

6

x

x

+

9

x  

(  

x  

+  

3  

)

+  

3  

(  

x  

+  

3  

)

=  

0

(  

x  

+  

3  

)  

(  

x  

+  

3  

)

=  

0

Nous associons maintenant le facteur à zéro pour obtenir la solution (les deux facteurs sont égaux ici).

x  +  3  =  0

x  = -  3  est la solution.

Explanation:

These facts suggest that the economic policy of the late 1980s could focus more on the subsidiary and market economy, with better coordination and that it would be more favored in saving and thinking about the stability of the financial and banking system.
