3+3x-14x-14=0
3x(x+1)-14x-14=0
(x+1)(3x-14)=0
x+1=0 3x-14=0
x=-1 x=
Объяснение:
3x^2 - 11x-14=0
3x^2 +3x - 14x - 14 = 0
3x(x + 1) - 14(x + 1) = 0
(x + 1)(3x - 14) = 0
x + 1 = 0; x₁ = -1
3x - 14 = 0; 3x = 14; x = 14/3; x₂ = 4 2/3
ответ:
D=b² - 4ac=11²+4*3*14=121+168=289=17²
x₁=(11+17)/6=28/6=14/3
x₂=(11-17)/6=-1
