Sagot :
[tex]\not(x+4)=\not(x+4)(x+4) \\\\ 0=(x+4) \\\\ 0=x+4 \\\\ \boxed{x=-4}[/tex]
Case 1:
[tex](x+4)=(x+4)(x+4)[/tex]
We divide both sides by (x+4)
[tex]1=x+4 \\ -3=x[/tex]
Case 2:
The value of x+4 is 0
[tex]x+4=0 \\ x=-4[/tex]
Therefore x is either -3 or -4.
[tex](x+4)=(x+4)(x+4)[/tex]
We divide both sides by (x+4)
[tex]1=x+4 \\ -3=x[/tex]
Case 2:
The value of x+4 is 0
[tex]x+4=0 \\ x=-4[/tex]
Therefore x is either -3 or -4.
