rascle Posted October 31, 2010 Share Posted October 31, 2010 Hi I have a user inputted value (e.g. "$value = "5x^2 - 6x - 5x + 9 = 72 - 5";") which is a Quadratic equation that needs balancing (for the example above I want to rearrange it so that the 72-5=67 and the 67 goes across the formula to make 5^x -11x -57 = 0). Does anyone have any ideas how I should go about doing this? I was going to use string functions to try and split the values apart and then add them to seperate variables to create the quadratic equation. Does anyone have any other / better ideas for this? Thanks Rhys Quote Link to comment Share on other sites More sharing options...
