The quadratic formula is a powerful tool used to solve quadratic equations of the form ax^2 + bx + c = 0. It allows us to find the roots or solutions of any quadratic equation, even if it cannot be easily factored.

The quadratic formula states that for any quadratic equation ax^2 + bx + c = 0, the solutions can be found using the formula:

x = (-b ± √(b^2 - 4ac)) / (2a)

Let's break down the formula and its application with an example:

Consider the quadratic equation 2x^2 + 5x - 3 = 0. We can identify the values of a, b, and c as a = 2, b = 5, and c = -3. Plugging these values into the quadratic formula, we get:

x = (-5 ± √(5^2 - 4(2)(-3))) / (2(2))

Simplifying further, we have:

x = (-5 ± √(25 + 24)) / 4

x = (-5 ± √49) / 4

This gives us the two solutions: x = (-5 + 7) / 4 = 2/4 = 1/2 and x = (-5 - 7) / 4 = -12/4 = -3.

By using the quadratic formula, we have successfully obtained the solutions to the given quadratic equation. Remember, this formula can be applied to any quadratic equation to find its solutions.
