Final answer:
The quadratic formula can be used to solve quadratic equations numerically.
Step-by-step explanation:
The solution or roots for any quadratic equation can be calculated using the quadratic formula. The quadratic formula states that if we have an equation of the form ax² + bx + c = 0, then the solutions for x can be found using the formula:
x = (-b ± √(b² - 4ac)) / 2a
This formula allows us to solve any quadratic equation numerically regardless of whether it can be factored or not.
