The first one can be written as a fraction because it is a repeating decimal.
The second one can be written as a fraction because it is a repeating decimal.
The third one can not be written as a fraction since it is nether terminating nor repeating.
The last one can be written as a fraction since it is a terminating decimal.
34255 = 5 * 13 * 17 * 31
203515 = 5 * 13 * 31 * 101
So GCD(34255, 203515) = 5 * 13 * 31 = 2015
Δ(discriminent) = b²-4ac
Calculate Δ of: -2x² + 6x +13, where:
a= -2
b=6
c=13
THEN Δ = 6² - 4(-2)(13) = 36 -4(-26) = 36 +104 and Δ = 140
