[tex]x = - 1 \\ x = \: 7[/tex]
Step-by-step explanation:
[tex]2(x - 3 {)}^{2} - 32 = 0[/tex]
[tex](x - 3 {)}^{2} - 16 = 0[/tex]
[tex](x - 3 - 4) \times (x - 3 + 4) = 0[/tex]
[tex](x - 7) \times (x + 1) = 0[/tex]
[tex]x - 7 = 0 \\ x + 1 = 0[/tex]
[tex]x = 7 \\ x + 1 = 0[/tex]
[tex]x = - 1 \\ x = 7[/tex]
