What will be an ideal response?
1) If the quadratic equation is of the type x2 = k, use the principle of square roots.
2) If the quadratic equation is of the type ax2 + bx + c = 0, b ? 0, use the principle of zero products, if possible.
3) If the quadratic equation is of the type ax2 + bx + c = 0, b ? 0, and factoring is difficult or impossible, use the quadratic formula.
