Question

|[x+2][x-5]]²⁰¹⁶=0

Answer 1

[( x + 2 )( x - 5 )]²⁰¹⁶ = 0

=> ( x + 2 )( x - 5 ) = 0

=> x + 2 = 0 hoặc x - 5 = 0

+) x + 2 = 0 => x = -2

+) x - 5 = 0 => x = 5

Vậy x = -2 hoặc  x = 5

Answer 2

\(\orbr{\begin{cases}x+2=0\\x-5=0\end{cases}\Rightarrow\orbr{\begin{cases}x=-2\\x=5\end{cases}}}\)

Answer 3

\(\left|\left(x+2\right)\left(x-5\right)\right|^{2016}=0\)

\(\Rightarrow\left(x+2\right)\left(x+5\right)=0\)

\(\Rightarrow\orbr{\begin{cases}x+2=0\\x-5=0\end{cases}}\)

TH1:

\(x+2=0\)

\(x=-2\)

TH2: 

\(x-5=0\)

\(x=5\)

\(\Leftrightarrow\orbr{\begin{cases}x=-2\\x=5\end{cases}}\)

Answer 4

\(\left|\left(x+2\right)\left(x-5\right)\right|^{2016}=0\)

\(\Rightarrow\left(x+2\right)\left(x-5\right)=0\)

\(\Rightarrow\hept{\begin{cases}x+2=0\\x-5=0\end{cases}\Rightarrow}\hept{\begin{cases}x=-2\\x=5\end{cases}}\)
