5 hours ago Quadratics Formula. The formula for a quadratic equation is used to find the roots of the equation. Since quadratics have a degree equal to two, therefore there will be two solutions for the equation. Suppose, ax² + bx + c = 0 is the quadratic equation, then the formula to find the roots of this equation will be: x = [-b±√ (b2-4ac)]/2.

  • 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 basic quadratic formula?

A quadratic equation is any polynomial equation of degree 2, or any equation in the form , or any equation that can be expressed in that form. The quadratic formula is a formula for solving any quadratic equation by completing the square on the equation , treating a, b, and c as constants.

What is the purpose of the quadratic formula?

The purpose of the quadratic formula is to solve quadratic equations. It is one of the rare occasions where we can fully understand the behavior of the solutions of an equation in a simple formula. ... The main purpose of the quadratic formula is to solve the quadratic equation (some times called finding a zero of the equation).

When should i use the quadratic formula?

The quadratic formula is used when you can’t factor a quadratic equation because it is non-factorable. For example: x^2–5x+3=0 is non factorable, you would have to use the quadratic formula to find the roots. P.S You could also find the roots of an equation by completing the square, or from the graph of the equation itself.
