## quadratic formula

### The quadratic formula is a formula that is used to solve quadratic equations, which are equations of the form ax^2 + bx + c = 0, where a, b, and c are constants and x represents the unknown variable

The quadratic formula is a formula that is used to solve quadratic equations, which are equations of the form ax^2 + bx + c = 0, where a, b, and c are constants and x represents the unknown variable. The quadratic formula is derived by completing the square on the quadratic equation.

The quadratic formula is:

x = (-b ± √(b^2 – 4ac)) / (2a)

In this formula, the symbol ± represents two possible solutions, one positive and one negative. The solutions represent the values of x that make the equation true.

To use the quadratic formula, you need to identify the values of a, b, and c from the given quadratic equation. Then, substitute these values into the formula and simplify the expression. Finally, calculate both solutions by using the plus and minus signs.

It’s important to note that the quadratic formula can solve any quadratic equation, regardless of the values of a, b, and c. It is a powerful tool in finding the roots of quadratic equations and determining the nature of their solutions, such as real or complex numbers.
