You can put this solution on YOUR website!
Solve by factoring completely
10t^2 - t - 2 = 0
Finding the coefficient of t is the trick here, factors of 10: 2 and 5
(_x + 1)(_x - 2)
If you know how to FOIL you can look at this and find the ones that fit
(5x+2)(2x-1) = 0
Two solutions
5x = -2
x = -2%2F5
and
2x = 1
x = 1%2F2
