Math Problem Statement
What is the formula X = b-/2a?
Solution
The formula you've written seems to be related to the quadratic formula, but it appears incomplete. Based on your notation, it likely refers to a part of the full quadratic formula used to solve quadratic equations of the form:
The complete quadratic formula is:
In this formula:
- , , and are the coefficients of the quadratic equation.
- The term indicates two possible solutions (one using and the other using ).
In your notation, , it looks like the minus sign is just part of , which is a part of the full formula.
