Penjelasan dengan langkah-langkah:
[tex]4 {x}^{2} - 12 x + 9 = 0[/tex]
[tex]4 {x}^{2} - 6x - 6x + 9 = 0[/tex]
[tex](4 {x}^{2} - 6x) + ( - 6x + 9) = 0[/tex]
[tex]2x(2x - 3) - 3(2x - 3) = 0[/tex]
[tex](2x - 3)(2x - 3) = 0[/tex]
[tex] {(2x - 3)}^{2} = 0[/tex]
[tex]2x - 3 = 0[/tex]
[tex]x = \frac{3}{2} [/tex]
