The Quadratic Formula: For ax2 + bx + c = 0, the values of x which are the solutions of the equation are given by: For the Quadratic Formula to work, you must have your equation arranged in the form "(quadratic) = 0". Also, the "2a" in the denominator of the Formula is underneath everything above, not just the square root.

How to solve quadratic formula?

  • 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.
  • Use quadratic formula if you couldn’t factorize the quadratic.
  • Quadratic formula: x = −b± b2−4ac√ 2a x = − b ± b 2 − 4 a c 2 a

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.
