Click the buttons and arrows to advance throughout the project. The "about" section talks about the quadratic formula. The "examples" section gives four different examples. The "calculator" section is a calculator for the quadratic formula.
NOTE: If the "sqrt" variable reads "NaN', the answers are false. This is because there are no rational number square roots of negative numbers. To avoid this, make either the "a" or "c" variable negative. Also note that if you make the "a" value negative, flip the positive/negative values of the answers.
