**Completing the square**

- Put the equation into the form ax 2 + bx = – c.
- Make sure that a = 1 (if a ≠ 1, multiply through the equation by before proceeding).
- 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.
- Find the square root of both sides of the equation.
- Solve the resulting equation.

- f ( x) = a ( x − h) 2 + k {displaystyle f (x)=a (x-h)^ {2}+k}
- 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} . ...
- To review how to complete the square, see Complete the Square.

- 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

**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]
