Is x positive? (1) |x^2| = 3 For sake of simplifying the calculation let us re frame the above eqn as |x^2|=4 ( it doesn't change the purpose ) The above eqn is true for both x= -2 and x=2 Hence Insufficient.

x^2+8x+15=0

Thus s-r = -3 - (-5)
= -3 + 5
= 2.

Ceilidh.erickson interchanged the s and r value while substituting at the end.. Rest of it was correct.
