Find the vertex of F(x) by using the formula for the x-coordinate of the vertex.

F(x)= 4x^2 - 3x - 6

I don't exactly understand this question. could someone clear it up and help me solve it? Thanks!!

factor it:

F(x)=4(x^2-3/4x ) -6
F(x)=4(x^2-3/4 x + 9/64) - 6 - 4*9/64
= 4(x-3/8)^2 -( )

Well,it is obvious that x=3/8 is the x vertix. Putting that x in, then y= -6-36/64

check my thinking.
