give me a sec.
Hi there c: \(\Large\rm ax^2+bx+c=0\) Notice that our quadratic formula has all pluses, no minus. So we'll want to write our quadratic like this: \(\Large\rm x^2+(-8)x+(-4)\) so we can more easily identify our b and c.
\(\Large\rm x=\dfrac{-(-8)\pm\sqrt{(-8)^2-4(1)(-4)}}{2(1)}\)Understand how I plugged all those values into the formula?
thanks\ (*>v<)/
