Are there any shortcuts to quadratic functions?
That is not the quadratic formula it is -b plus or minus, b squared – 4(ac) all over 2a, you would best to just look up the quadratic formula to understand it, you can also use factorization, or completeing the square, but must have a coefficient of one. For larger pol nomials there are other ways, but just best to google it or yahoo it considering the site i am on.
