and i go to football not only at school and to sport school . i like play football . bye Rob. From your friend
log(3x - 11) + log(x - 27) = 3
log[(3x - 11)(x - 27)] = 3
(3x - 11)(x - 27) > 0 <=> 3x^2 - 92x + 297 > 0
1. 3x - 11 > 0 => x > 11/3 => x > 27
x - 27 > 0 => x > 27
2. 3x - 11 < 0 => x < 11/3
x - 27 < 0
=>
одз x ∈(-∞; 11/3) & (27; +∞)
т.к. основание не указанно и написано log делаю вывод, что основание 10
3x^2 - 92x + 297 = 1000
3x^2 - 92x - 703 = 0
D = 92^2 + 4*3*703 = 16900 = 130^2
x1 = (92 - 130) / 6 = -19/3 оба икса подходят под одз
x2 = (92 + 130) / 6 = 37
