Question 17

If $r_1$ and $r_2$ are the distinct real roots of $x^2+px+8=0,$ then it must follow that:
  1. $\lvert r_1+r_2\rvert\gt4\sqrt2$
  2. $\lvert r_1\rvert\gt3$ or $\lvert r_2\rvert\gt3$
  3. $\lvert r_1\rvert\gt2$ and $\lvert r_2\rvert\gt2$
  4. $r_1\lt0$ and $r_2\lt0$
  5. $\lvert r_1+r_2\rvert\lt4\sqrt2$
