@daring glen for thé exercice 1 is just

Résolve inéquation

[daring glen]

Okay 1

$-7x^2 + 17x - 6 = 0 \ \ D = 17^2 - 4 × (-7) × (-6) = 289 - 168 = 121 \ \ x_1 = \frac{-b - \sqrt{D}}{2a} = \frac{-17 - 11}{-14} = 2 \ \ x_2 = \frac{-b + \sqrt{D}}{2a} = \frac{-17 + 11}{-14} = \frac{6}{14} = \frac{3}{7} \ \ \ \frac{2x - 3}{-7x^2 + 17x - 6} = \frac{2x - 3}{-7(x - 2)\qty(x - \frac{3}{7})} \ \ \frac{2x - 3}{-7(x - 2)\qty(x - \frac{3}{7})} < 0$

Fuck

$2x - 3 = 0 \Rightarrow x = \frac{3}{2} \ \ x - 2 = 0 \Rightarrow x = 2 \ \ x - \frac{3}{7} = 0 \Rightarrow x = \frac{3}{7}$
