x^2/3-x-1/6 -b+-sqr rt of b^2-4ac/ 2a
a=? b=-1 c=-1/6
I am stuck as to what "a" is.
--------------
If it's
, then a = 1/3
To solve it, multiply by 6
2x^2 - 6x - 1 = 0

SOLVE quadratic equation (work shown, graph etc)
Quadratic equation
(in our case
) has the following solutons:
For these solutions to exist, the
discriminant
should not be a negative number.
First, we need to compute the discriminant
:
.
Discriminant d=44 is greater than zero. That means that there are two solutions:
.
Quadratic expression
can be factored:
Again, the answer is: 3.1583123951777, -0.1583123951777. Here's your graph:
