Question

(x-3/2)² =9/16

Answer 1

\(\left(x-\frac{3}{2}\right)^2=\frac{9}{16}\)

\(\Rightarrow\left(x-\frac{3}{2}\right)^2=\frac{3}{4}^2\) hoặc \(\left(x-\frac{3}{2}\right)^2=\left(-\frac{3}{4}\right)^2\)

\(\Rightarrow x-\frac{3}{2}=\frac{3}{4}\) hoặc \(x-\frac{3}{2}=-\frac{3}{4}\)

\(\Rightarrow x=\frac{9}{4}\) hoặc \(x=\frac{3}{4}\)

Ai thấy đúng thì ******** nha

Answer 2

  (x-3/2)²=9/16

  (x-3/2)²=(3/4)²

  x-3/2=3/4

  x     =3/4+3/2

  x     =9/4

Answer 3

Có 2 trường hợp :

TH1: (x - 3/2)^2 = (3/4)^2

<=> x - 3/2 = 3/4

<=> x = 3/4 + 3/2

<=> x = ........Tự tính nhá!

TH2: (x - 3/2)^2 = (-3/4)^2

<=> x - 3/2 = -3/4

<=> x = -3/4 + 3/2

<=> x =..........Tự tính nhé!

Vậy có 2 giá trị là ..............

Answer 4

Có ( x -  \(\frac{3}{2}\) )² =  \(\frac{9}{16}\)

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

\(\Rightarrow\) x - \(\frac{3}{2}=\frac{3}{4}\)

      x        \(=\frac{3}{4}+\frac{3}{2}\)

      x        \(=\frac{9}{4}\)

Answer 5

Ta có:(x-3/2)^2=9/16

                      =3/4.3/4

                       =3/4^2

Suy ra:x-3/2=3/4   hoac   x-3/2=-3/4

                x=3/4+3/2             x=-3/4+3/2

                x=9/4                    x=3/4
