I needed to type the questions again because there was a typing mistake this morning when I originally posted the math questions.
QUESTION 1:
If a > 0, show that the solution set of the inequality x^2 < a consists of all numbers x for which -(sqrt{a}) < x < (sqrt{a}).
QUESTION 2:
If a > 0, show that the solution set of the inequality x^2 > a consists of all numbers x for which x > (sqrt{a}) OR x < -(sqrt{a}).
I hope this makes sense now.
Thanks.
