1-47.

Although the Quadratic Formula always works as a strategy to solve quadratic equations, it is not always the most efficient method. For example, sometimes, a faster method is to factor and use the Zero Product Property. For each equation below, choose the method you think is most efficient to solve the equation.

Note the expression in this equation can be factored.

Notice that

is a perfect square.

Note the expression in this equation cannot be factored.

Adding

to both sides will create a perfect square.
