  • [tex] {x}^{2} + 6 = 42[/tex]

  • [tex] {x}^{2} = 42 - 6[/tex]

  • [tex] {x}^{2} = 36[/tex]

  • [tex]x = \sqrt{36} [/tex]

  • [tex]x = \pm6[/tex]

Solution:

[tex] {x}^{2} + 6 = 42 \\ = > {x}^{2} = 42 - 6 \\ = > {x}^{2} = 36 \\ = > x = \sqrt{36} \\ = > x = \sqrt{6 \times 6} \\ = > x = \sqrt{ {6}^{2} } \\ = > x = ±6[/tex]

Answer:

±6
