Given:

To find:
The interval on which the given function is positive.
Solution:
We have,

Splitting the middle term, we get




Using zero product property, we get


-2 and 7 divide the number line is three interval.
Interval Signs of
Result
(-∞,-2) (-)(-)(-) Negative
(-2,7) (-)(-)(+) Positive
(7,∞) (-)(+)(+) Negative
So, the function is positive for the interval (-2,7), i.e., -2 < x < 7.
Therefore, the correct option is D.
