Question

Помогите пожалуйста!!!!

Answer 1

$\frac{(2-x^2)(x-3)^2}{(x+1)(x^2-3x-4)} \geq 0\\ \\ \frac{(x^2-2)(x-3)^2}{(x+1)(x^2+x-4x-4)}\leq0 \\ \\ \frac{(x+\sqrt{2} )(x-\sqrt{2})( x-3)^2}{(x+1)^2(x-4)}\leq 0\\ \\ ---[-\sqrt{2}}]+++(-1)+++[ \sqrt{2} ]---[3]---(4)\\ \\ x\in(-oo;-\sqrt{2} ]U[\sqrt{2} ;4)$
