Question

\(*=^=*)/ please help .Use the quadratic formula to solve the quadratic equation x2 − 8x − 4 = 0.

Answer 1

give me a sec.

Answer 2

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.

Answer 3

\(\Large\rm x=\dfrac{-(-8)\pm\sqrt{(-8)^2-4(1)(-4)}}{2(1)}\)Understand how I plugged all those values into the formula?

Answer 4

thanks\ (*>v<)/
