The quadratic equation

can be written in the form:

Where p and q are the roots of the equation.
Given p = 4, q = -2, a = 3, the quadratic will look like this:

Finally, distribute and combine like terms to put it in standard form.
I believe it is 18 because GF is half the length of CG if CG equals 12 then GF equals 6 add them together and you get CF equals 18.
It could possibly be the first on but I’m not completely sure
