Provide an appropriate response.Explain in your own words a sequence of steps that can be used to solve any quadratic equation in the most efficient way.
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.
