You can factor out the two, so you get 2(x^2-9). You can simplify it more because it is a difference of squares, so it should be 2(x-3)(x+3)
14gallons=380miles
14/380=<span>0.03684210526gallons/mile
</span>
418*<span>0.03684210526=15.4gallons
</span>
or you could cross multiply
14gallons=380miles
x gallons=418miles

380x=5852
divide both sides by 380
x=15.4 gallons
