Решите квадратные неравенства с помощью графика квадратичной функции:
(отдаю все баллы ибо срочно надо)
1) [tex] x^{2} -14x+49 \leq 0[/tex]
2) [tex]4 x^{2} -20x+25\ \textless \ 0[/tex]
3) [tex]3 x^{2} -5x-2\ \textgreater \ 0[/tex]
4) [tex]-4 x^{2} +3x+1 \leq 0[/tex]
5) [tex] x^{2} +6x+10\ \textless \ 0 [/tex]
6) [tex] x^{2} +3x+5\ \textless \ 0[/tex]
7) [tex]4 x^{2} -8x+9\ \textgreater \ 0[/tex]
8) [tex]9 x^{2} -25\ \textgreater \ 0[/tex]
9) [tex] x^{2} -3x-4\ \textless \ 0[/tex]
10) [tex]3 x^{2} +2x+4 \geq 0[/tex]
11) [tex] \frac{1}{3} x^{2} +2x \leq -3[/tex]
