### How do you solve a quadratic formula?

Step by step guide to Solving a Quadratic Equation

• Write the equation in the form of: ax2 + bx + c = 0 a x 2 + b x + c = 0
• Factorize the quadratic and solve for the variable.
• Quadratic formula: x = − b ± √b2 − 4ac 2a x = − b ± b 2 − 4 a c √ 2 a

### Which are the solutions of the quadratic formula?

The solutions to the quadratic equation are the values of the unknown variable x , which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

### What is the correct quadratic formula?

The quadratic formula is a technique that can be used to solve quadratics, but in order to solve a quadratic using the quadratic formula the problem must be in the correct form. To solve a quadratic using the quadratic formula the quadratic must be in the form ax2 + bx + c = 0.

### Why should i know the quadratic formula?

The quadratic equation is used in the design of almost every product in stores today. The equation is used to determine how safe products are and the life expectancy of products, such as when they can expect to quit working. Designers can then see what needs to be changed in the product to make it last longer.
