I got as far as -2.2x10^2 + or - square root of 9.64x10^-4 and then don't know what to do or if it is right. PLEASE HELP!! I need to get comfortable with the quadratic equation. Thank you! Answer by josgarithmetic(39617) (Show Source):
You can put this solution on YOUR website! You have the values for a, b, and c, and you have these from a quadratic equation based on general form ;
just use the values in the general solution. Simplify and compute! What is the result?
