you have to use the quadratic formula. Your equation is in the form of ax^2 bx c
The quadratic formula is -b – sqrt(b^2-4ac)/2a
so you have (-6 – sqrt(36-144))/8
-6 – sqrt(-108)/8
this actually has no solution as you cant take the square root of a negative number. This means that the graph does not touch the x-axis.
