y = (5x + 2)(3x - 4)
Can you take it from there?
P.S. racer717 is close, but did not give the correct answer.

The easiest thing to do is to look at the factors of 15 and 8:
3,5 and 2,4
5*4 - 3*2 = 14, so this should work:
y = (3x-4)*(5x+2)
So the roots are -2/5 and +4/3

15x^2 - 14x - 8 = 0
(5x + 2)(3x - 4) = 0
5x = -2; x = -2/5 or
3x = 4; x = 4/3

(5x+2)(3x-4)=0
x= -2/5 x=4/3

y=(3x-4)(5x+2)
(5x+2)(3x-4)=0
5x+2=0
3x-4=0
x=-2/5 or 4/3

y=x-16. I hope.
