Answer:

[tex]x( - 3and4)[/tex]

[tex]x {}^{2} - x - 12 = 0 \\ x = \frac{ - ( - 1) + \sqrt{( - 1) {}^{2} - 4 \times 1( - 12) } }{?2} \\ x = \frac{1 + 7}{2} \\ x = 4 \\ x = - 3 \\ (x - 4)(x + 3) < 0 \\ x - 4 > 0 \\ x + 3 < 0 \\ xe0 \\ x + 3 > 0 \\ x - 4 < 0 \\ \: de \: solution \: satisfying \: both \: enquities \: is \: x( - 3and4)[/tex]
