The solutions or roots to this equation is found by solving for x. We can do this a couple ways either by FOIL or quad formula
3x^2+6x+6=0
3(x^2+2x+2)=0
x^2+2x+2=0 we cant FOIL this out so we use the quad formula
x= [(-b+\-sqrt(b^2-4ac))/2a]
x= -2+\- sqrt(4-4(1)(2))/2(1)
x= -1 +i , -1 - i
So we have complex roots since our quad formula returned a negative number. Whenever the quad formula answer is positive we have two roots/solutions, when it is zero we have one root/solution, and whenever it is negative we have Complex roots/solutions
Hope this helps. Any questions please just ask. Thank you.

The cities are 14.7 inches apart on the map.
An inch on the map is 10 miles on the ground. That is what a scale of 1 in : 10 miles means.
If a distance is 147 miles on the ground therefore, on the map it will be:
= Distance on map / conversion factor
= 147 / 10
= 14.7 inches
The distance between the two cities on the map is 14.7 inches.
