Mammals are almost always born live from the mother.
<span>1st train DATA:
rate = 50 mph ; time = x hrs ; distance = rt = 50x miles
2nd train DATA:
rate = 55 mph ; time = (x-(1/2)) hrs ; distance = rt = 55(x-(1/2)) miles
Equation:
distance = distance
50x = 55(x-(1/2)
50x = 55x - (55/2)
-5x = -55/2
x = 11/2
x = 5 1/2 hrs (time at which the 2nd train overtakes the 1st train)

Which equations? I think you forgot to post a picture.
6x² -17x +5 = (6x² - 2x) - (15x + 5) (factoring by grouping)
2x (3x -1) - 5(3x - 1)
(2x -5) (3x - 1) is your final answer
hope this helps
