Question 1011501
Let's first isolate x^2


9 - x^2 < 0
9 - x^2+x^2 < 0+x^2
9 < x^2
x^2 > 9


Now we will apply the square root function to both sides


x^2 > 9
sqrt(x^2) > sqrt(9)
|x| > 3 ... take note of the absolute value


The inequality |x| > 3 breaks down into these two inequalities


x > 3 or x < -3


So the answer is choice B
