Final answer:
The Square Root method can only sometimes be used to solve a quadratic equation, specifically when the equation is a perfect square trinomial.
Step-by-step explanation:
The Square Root method can sometimes be used to solve a quadratic equation of the form ax2 + bx + c = 0. When the quadratic equation is a perfect square trinomial, such as (x + a)2 = b, taking the square root of both sides is an effective way to solve for x. However, for general quadratic equations, other methods such as factoring, completing the square, or using the quadratic formula might be necessary. Remember, when you take the square root of a squared term, you must consider both the positive and negative roots to find all possible solutions for x.
