Alan shoud use mean and range, mean is where you add all of the numbers up and divide by how many numbers there are, and range where you take the highest number and subtract it by the lowest number. This way he will find the greatest and least number of pins he knocked down
Add 10 on both sides
6x^2+12x+12=0.
Divide by 6 on both sides.
X^2+2x+2=0
Plug into quadratic formula
X=(-2 +\- (2^2-4•1•2))^1/2) /2•1
X=(-2 +\- (-4)^1/2)/2
X=(-2+\- 2i) /2
X=-1+\- I
X= -1 + i OR -1 - i
