ПОМОГИТЕ!!!! СРОЧНОООО!!!!!!!!

Answer 1

$\frac{5x^{2}+35x-2x^{2}+98-3x-21}{x(x-7)(x+7)}=\frac{3x^{2}+32x+77} {x(x-7)(x+7)}=\frac{3(x+\frac{11}{3})(x+7)} {x(x-7)(x+7)}=\frac{3x+11}{x^{2}+7x}$

D=1024-924=√100=10

x₁=$-\frac{32-10}{6}=-\frac{42}{6}=-7$

x₂=$-\frac{32+10}{6} =-\frac{22}{6}=-\frac{11}{3}$

Ответ: $\frac{3x+11}{x^{2}+7x}$
