Hi

solve this by factoring

 2x^2-11x+15=0

 2x^2 -11x = -15

 2[(x-11/4)^2 - 121/4] = -15

 (x-11/4)^2 = -15/2 + 121/16 = 1/16

   x - 11/4 = ± 1/4

       x = 11/4 ± 1/4

       x = 12/4 = 3

       x = 10/4 = 5/2



CHECKING our Answer***   |x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+

 x = +%2811+%2B-+sqrt%281%29%29%2F%284%29+
