For a quadratic equation ax^2 + bx + c = 0, the discriminant is given by b^2 - 4ac
Thus for a^2 - 2a + 5 = 0,
a = 1, b = -2 and c = 5
b^2 - 4ac = (-2)^2 - 4(1)(5) = 4 - 20 = -16

Answer:
he put 3 in the bag because 12 divided by 4 is 3 brainliest please? ^.^
Step-by-step explanation:
Answer:
If gas costs $3.75 per gallon and Berto has $12, then he can purchase 12/3.75 gallons. This is approximately 3.2 gallons. So the coordinate on this line would be (3.2, 12).
Actually... It's from web
Answer:
-4 seconds
Step-by-step explanation:
The question says he lost 8 seconds off the leader for each of the 3 pit stops that he made
8 x 3 = 24
This means that 24 seconds was lost.
If 10 seconds were gained for the next 2 pit stops, the driver gained a total of
2 x 10 = 20seconds
The amount of time he is off leader =
20 -24
= -4 seconds
We have it that -4 seconds represents time he is off the leader.
Thank you!
