Question 470734
If you already have the root of the quadratic


*[tex \LARGE x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}]


and you want a decimal answer, simply evaluate the expression (make sure to do the operations in the right order).If you have a graphing calculator, you can define a multi-variable function and use that (the syntaxes can differ from calculator to calculator).
