Question

[nguyễn việt hà]

Tìm x:

(x-4)²-48=-12

Answer 1

[Tung Duong]

\(\left(x-4\right)^2-48=-12\) 

\(\left(x-4\right)^2=-12+48\)

\(\left(x-4\right)^2=36\)

\(\left(x-4\right)^2=6^2\) 

\(\Rightarrow x-4=6\)

\(\Rightarrow x=6+4\)

\(\Rightarrow x=10\)

Answer 2

[Đỗ Thị Kim Anh]

(x-4)²-48=-12

(x-4)^{2=  (-12 ) +48}

(x-4)^{2= 36}

36 = 6²

^{=> x - 4 = 6}

^{x = 6 +4}

^{x = 10}
