Enter the variables a, b, and c into the calculator below to calculate the two solutions to completing the square.
Completing The Square Formula
When completing the square, the above formula is used where, a, b, and c are variables from the equation
How to complete the square
- First, determine the variables
Calculate or gather the variables a,b, and c from an equation of the form ax^2+bx+C.
- Enter the variables into the formula or calculator above.
The solution should be two separate answers, typically the x intercepts.
Completing the square is another way of saying using the quadratic equation to solve for the x-intercepts of an equation in the form mentioned above.
