Pzzz and explain< wll give brainiest to the best answer with explanation. (x+3)(x+1)> 0, solve the quadratic inequality and answer in interval notation. ps. i know the answer but i need explanation

(x + 3)(x + 1) > 0

x + 3 > 0 or x + 1 > 0

x > -3 x > -1

(-3, ∞) ∪ (-1, ∞)

This shows that you have to separate the two factors in order to find the solution to the quadratic inequality.

linear pair postulates
