Răspuns: [tex]\bf \text{\bf Solutia negativa este: } \red{\underline{-5}}[/tex]
Explicație pas cu pas:
[tex]\bf (x+1)^2=16[/tex]
[tex]\bf (x+1)^2=\sqrt{16}\implies |x+1|=4[/tex]
[tex]\bf x+1=4\implies x=4-1\implies \underline{x = 3}[/tex]
[tex]\bf x+1=-4\implies x=-4-1\implies \red{\underline{x = -5}}[/tex]
