Let p, q Î R. If 2 – 3 is a root of the quadratic equation, x 2 + px + q = 0, then:

Question:

Let $p, q \in R$. If $2-\sqrt{3}$ is a root of the quadratic equation, $\mathrm{x}^{2}+\mathrm{px}+\mathrm{q}=0$, then:

  1. $\mathrm{p}^{2}-4 \mathrm{q}+12=0$

  2. $\mathrm{q}^{2}-4 \mathrm{p}-16=0$

  3. $\mathrm{q}^{2}+4 \mathrm{p}+14=0$

  4. $p^{2}-4 q-12=0$
