1. Put the equation into the form ax 2 + bx = – c.
2. Make sure that a = 1 (if a ≠ 1, multiply through the equation by before proceeding).
3. Using the value of b from this new equation, add to both sides of the equation to form a perfect square on the left side of the equation.
4. Find the square root of both sides of the equation.
5. Solve the resulting equation.
6. f ( x) = a ( x − h) 2 + k {\displaystyle f (x)=a (x-h)^ {2}+k}
7. If your function is already given to you in this form, you just need to recognize the variables a {\displaystyle a} , h {\displaystyle h} and k {\displaystyle k} .
8. To review how to complete the square, see Complete the Square.
9. The roots of quadratic equation are equal in magnitude but of opposite sign if b = 0 and ac < 0
10. The root with greater magnitude is negative if the sign of a = sign of b × sign of c
11. If a > 0, c < 0 or a > 0, c > 0; the roots of quadratic equation will have opposite sign
12. If y = ax2+ bx + c is positive for all real values of x, a > 0 and D < 0
13. 3x 2 + 7x – 3 = x 2 + 2x + 6 [original equation]
14. 2x 2 + 7x – 3 = 2x + 6 [after subtracting x 2 from both sides]
15. 2x 2 + 5x – 3 = 6 [after subtracting 2x from both sides]
16. 2x 2 + 5x – 9 = 0 [after subtracting 6 from both sides]

  • To review how to complete the square, see Complete the Square.

What is the correct quadratic formula?

  • The roots of quadratic equation are equal in magnitude but of opposite sign if b = 0 and ac < 0
  • The root with greater magnitude is negative if the sign of a = sign of b × sign of c
  • If a > 0, c < 0 or a > 0, c > 0; the roots of quadratic equation will have opposite sign
  • If y = ax2+ bx + c is positive for all real values of x, a > 0 and D < 0

What does quadratic formula give us?

To convert it to standard form, we need to take a few steps:

  • 3x 2 + 7x – 3 = x 2 + 2x + 6 [original equation]
  • 2x 2 + 7x – 3 = 2x + 6 [after subtracting x 2 from both sides]
  • 2x 2 + 5x – 3 = 6 [after subtracting 2x from both sides]
  • 2x 2 + 5x – 9 = 0 [after subtracting 6 from both sides]
