Answer:
4
Step-by-step explanation:
The factors of 16 are:1 2 4 8 16
the factors of 28 are:1 2 4 7 14 28
the factors of 48 are: 1 2 3 4 6 8 12 16 24 48
and so the common factors are :1 2 4 the greatest one is 4 and so the answer is 4
x³ + 2x² - x - 2 < 0
x³ - x + 2x² - 2 < 0
x(x² - 1) - 2(x² - 1) < 0
(x - 2)(x² - 1) < 0
(x - 2)(x - 1)(x + 1) < 0
by chacking we get the solution
x ∈ (-∞,-1) ∪ (-1,1)
This is a combination question
Hope this helps
