Step-by-step explanation:

[tex]x { }^{2} + 7x = 12[/tex]

[tex]x {}^{2} + 7x - 12 = 0[/tex]

[tex]x = - 7 \sqrt{7 {}^{2} } - 4x1x( - 12) \div 2 \times 1| [/tex]

[tex]x = - 7 \sqrt{49 + 48 \div 2} [/tex]

[tex]x = - 7 \sqrt{97 \div 2} [/tex]

[tex]x = - 7 + \sqrt{97 \div 2} [/tex]

[tex]x = - 7 - \sqrt{97 \div 2} [/tex]

alternative form

[tex]x = - 8.42443 \\ [/tex]

[tex]x = 1.42443[/tex]
