Final answer:
The first step in solving a quadratic equation is setting the equation equal to zero, which is crucial for applying the quadratic formula to find solutions.
Explanation:
The first step in solving a quadratic equation is: Setting the equation equal to zero. This step is essential because it allows us to create an equation in the form ax² + bx + c = 0, which is needed to apply the quadratic formula.
For instance, if we start with an equation like 2x² + 5x - 3 = 0, the initial step would be to set the equation equal to zero, yielding 2x² + 5x - 3 = 0.
By setting the equation equal to zero, we lay the groundwork for applying the quadratic formula to find the solutions for the unknown variable.
