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

+

N  

2

=

b

=

6

Après avoir essayé quelques chiffres, nous obtenons  

N  

1

=

3

et  

N  

2

=

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.

jekas [21]

Answer:

Explanation: The impact of the change of power from the Kshatriyas to the Brahmins In Aryan society, occurred through the Caste System, which was intended to give each person their place in society. For this reason, the Kshatriyas belonged to a caste of rulers and warriors and were inferior to that of the Brahmins, who were generally ranked as priests and spiritual leaders and who possessed the highest rank within the caste system, since they were considered beings supreme These two types of systems were the highest in India.

Which two excerpts from Baseball Saved Us represent cause-and-effect relationships?
MAXImum [283]

Answer:

"Back in school, before Camp, I was shorter and smaller than the rest of the kids. I was always the last to be picked for any team when we played games."

"‘…America is at war with Japan, and the government thinks that Japanese Americans can’t be trusted.’"

Explanation:

Although you did not present the excerpts to which the question refers, we can consider the two options selected above to be the correct answers. This is because cause and effect relationships are those where one element causes another element to occur. In this case, in the first option, we can see that the narrator was always the last one to be chosen for the teams (effect) because he was the smallest child in the camp (cause). In the second option, we can see that no one trusted Japanese-American citizens (effect) because the American government was at war with Japan (cause).
