Answer:
6x² + 5x - 2 = 0
Step-by-step explanation:
Given
2x² - 5x - 6 = 0 ← in standard form
with a = 2, b = - 5, c = - 6, then
sum of roots α + β = - =
product of roots = = - 3, then
sum of new roots = +
=
= = -
product of new roots = ×
= = -
Hence the required equation is
x² + x - = 0 or
6x² + 5x - 2 = 0 ( multiplying through by 6 )
Answer:
- speed of the first bus: 36 2/3 miles per hour
- speed of the second bus: 73 1/3 miles per hour
Step-by-step explanation:
The second bus travels twice as fast, so will take half the time of the first bus. The second bus takes 3 hours less time, so that is half the time of the first bus.
The first bus's speed is (220 mi)/(6 h) = 36 2/3 mph.
The second bus's speed is twice that: 73 1/3 mph.
