Best ResponseYou've already chosen the best response.0now draw a line of numbers, mark 3 and 1 on it. If you are at infinity till 3 then both factors are negative. Between 3 and 1 x1 is negative x+3 is positive. After 1 both are positive. Now when will you get something lower than 0? When you multiply *+ (*=+, +*+=+) So the answer is x is greater/equal than 3 and lower/equal than 1.
