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 )
The answer is a total of 9 hours
