Respuesta :

Let the no be x=x**2=2**2=4 plus the no,4+2=6

Answer:

2 or - 3

Step-by-step explanation:

Here, s represents the unknown number,

Since, square of s = [tex]s^2[/tex]

So, the square of s plus s = [tex]s^2+s[/tex]

According to the question,

[tex]s^2+s=6[/tex]

[tex]s^2+s-6=0[/tex]

By middle term splitting,

[tex]s^2+3s-2s-6=0[/tex]

[tex]s(s+3)-2(s+3)=0[/tex]

[tex](s-2)(s+3)=0[/tex]

[tex]\implies s=2\text{ or }-3[/tex]

Hence, the number would be 2 or -3.
