**What Equation (s)??**

- ax^2 + bx + c = 0 - very versatile
- (a+bt)2+ (c+dt)2= (e+ft)2 - length of solar eclipses
- h+Vt- (1/2)gt^2 - Vertical motion under gravity

- 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.

**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.
