first you need to re-arrange the equation so it looks like ax^2 + bx + c =0 so first add 2 to each side of the equation.... post the result here..

The quadratic calculator will find the value of x for a quadratic formula. Finding the quadratic value is so tough because of its tough formula. Using this quadratic calculator you can now do this so easily without remembering the quadratic formula. http://www.acalculator.com/quadratic-equation-calculator-formula-solver.html

@Courtney This question is not about getting the answer Tis is about becoming familiar with the structure of quadratics, and also recognising the correct values of a,b and c Using the calculator FIRST REQUIRES that you understand the format of the equation. This forum is meant to be about learning and guidance - your answer does not help the poster in any way if he does not recognise a quadratic and its terms correctly.
