4 hours ago Given a quadratic equation equal to zero you can factor the equation and set each factor equal to zero. To factor you have to find two numbers that multiply to make 9 and add to make 6. The number is 3. So the factored form of the problem is (x+3) (x+3)=0. This statement is true only when x+3=0. Solving for x gives x=-3.

Frequently Asked Questions

How to write a quadratic formula?

Summary

  • Quadratic Equation in Standard Form: ax 2 + bx + c = 0
  • Quadratic Equations can be factored
  • Quadratic Formula: x = −b ± √ (b2 − 4ac) 2a
  • When the Discriminant ( b2−4ac) is: positive, there are 2 real solutions zero, there is one real solution negative, there are 2 complex solutions

How to solve with the quadratic formula?

Step by step guide to Solving a Quadratic Equation

  • Write the equation in the form of: [Math Processing Error] 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: [Math Processing Error] 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.

When do you 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.
