bantu jawab dong kak
Penjelasan dengan langkah-langkah:
[tex] {x}^{2} - 3 = 4(x - 2)[/tex]
[tex] {x}^{2} - 3 = 4x - 8[/tex]
[tex] {x}^{2} - 4x = - 8 + 3[/tex]
[tex] {x}^{2} - 4x = - 5[/tex]
[tex] {x}^{2} - 4x + 4 = - 5 + 4[/tex]
[tex] {(x - 2)}^{2} = - 1[/tex]
[tex]x - 2 = \pm \sqrt{ - 1} [/tex]
[tex]x = \pm i + 2[/tex]
[tex]x = - i + 2 \: \text{atau} \: i+ 2[/tex]
