%28%28x+%2B+1%29%2F%282x+%2B+4%29%29+%3E=+3, x+%3C%3E+2

%28%28x+%2B+1%29%2F%282x+%2B+4%29%29+-3%3E=+0

%28%28x+%2B+1%29%2F%282x+%2B+4%29%29+-3%282x+%2B+4%29%2F%282x+%2B+4%29%3E=+0

%28%28x+%2B+1%29+-3%282x+%2B+4%29%29%2F%282x+%2B+4%29%3E=+0

%28x+%2B+1+-6x+-12%29%2F2%28x+%2B+2%29%3E=+0

%28-5x+-11%29%2F2%28x+%2B+2%29%3E=+0

x%3C=-11%2F5

solutions:

%28-5x+-11%29%3E=+0=>x%3C=-11%2F5

2%28x+%2B+2%29%3E=+0=>%28x+%2B+2%29%3E=+0=>x+%3E=+-2

-11%2F5%3C=x%3C-2
interval:
[-11%2F5, -2)
