## Conversion formula
The conversion factor from gallons to liters is 3.7854118, which means that 1 gallon is equal to 3.7854118 liters:
1 gal = 3.7854118 L
To convert 138.3 gallons into liters we have to multiply 138.3 by the conversion factor in order to get the volume amount from gallons to liters. We can also fo... | HuggingFaceTB/finemath | |

### How To Calculate Percentages
One of the most valuable skills in Maths EVER, am I right?

# Is it possible to factor y=9x^2-48x+64? If so, what are the factors?
Aug 25, 2016
Yes
#### Explanation:
If you are having a problem factorising a quadratic by inspection then use the formula
$x = \frac{- b \pm \sqrt{{b}^{2} - 4 a c}}{2 a}$
In this example the discriminant ${b}^{2} - 4 a c$=0
So the factors are t... | HuggingFaceTB/finemath | |
