Question

tìm x: (x-1)²= \(\left|\frac{1}{4}-\frac{1}{2}-\frac{3}{4}\right|\)

Answer 1

\(\left(x-1\right)^2=\left|\frac{1}{4}-\frac{2}{4}-\frac{3}{4}\right|=\left|-1\right|=1\)

x-1=1 hoặc x-1=-1

x=2 hoặc x=0

Answer 2

=> (x-1)² = /-1/

(x-1)² = 1

(x-1)²= 1²

=> x-1 = 1

     x    = 1 +1

     x = 2

Vậy x = 2
