2x² - 3 = 0 kuadrat sempurna
![]()
Penjelasan dengan langkah-langkah:
[tex]2 {x}^{2} - 3 = 0[/tex]
[tex]2 {x}^{2} = 3[/tex]
[tex] {x}^{2} = \frac{3}{2} [/tex]
[tex]x = \pm \sqrt{ \frac{3}{2} } [/tex]
[tex]x = - \sqrt{ \frac{3}{2} } \: \text{atau} \: \sqrt{ \frac{3}{2} } [/tex]
[tex] {2x}^{2} - 3 = 0 \\ 2 {x}^{2} = 3 \\ {x}^{2} = \frac{3}{2} \\ {x}^{2} - \frac{3}{2} = 0 \\ (x + \sqrt{ \frac{3}{2} } )(x - \sqrt{ \frac{3}{2} } ) = 0 \\ x = - \sqrt{ \frac{3}{2} } \: \: or \: \: x = \sqrt{ \frac{3}{2} }[/tex]
