Дальше надо вынести общий множитель из первых двух членов и последних двух: 9x(x+1)-корень из 2(x+1)=0;
(x+1)(9x-корень из 2) = 0
x+1 = 0 или 9x-корень из 2 = 0
x = -1 9x = корень из 2 |^2
81x^2 = 2
x^2 = 2/81
x = ± корень из 2/81 или ± 1/3 на корень из 2/9
По теореме Виета:
x₁+x₂=-p ⇒ p=-(x₁+x₂)=-(-8+5)=3
ответ: p=3
