Identifying the Most Appropriate Method for , , and
Determine the most appropriate solving method for each quadratic equation by examining its structure:
ⓐ
This equation has the form — the squared variable term is on one side and a constant is on the other, with no linear term. The most appropriate method is the Square Root Property.
ⓑ
The left side of this equation is a perfect square trinomial, since . Because the trinomial factors readily, the most appropriate method is Factoring.
ⓒ
First, write the equation in standard form: . Although factoring might be attempted first, considering all the trial-and-error possibilities needed for a leading coefficient of and a constant of makes it impractical. The most appropriate method is the Quadratic Formula.
