Answer 1

Step-by-step explanation:

We have,

$\frac{( {x}^{2} - x + 1) ({x}^{2} - 4) }{( {x}^{2} - 3x + 2)(x + 7)} \leqslant 0$

since, (x² - x + 1) is always positive, so we have the following inequality

$\frac{(x + 2)(x - 2)}{(x - 2)(x - 1)(x + 7)} \leqslant 0$

$x \in( - 7 \: to \: - 2] \: or \: x \in(1 \: to \: 2)$
