15x=2x%5E2%2B16
0=2x%5E2-15x%2B16
or
2x%5E2-15x%2B16=0........compare to ax%5E2%2Bbx%2Bc=0, you see that a=2, b=-15, and c=16
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
x+=+%28-%28-15%29+%2B-+sqrt%28+%28-15%29%5E2-4%2A2%2A16+%29%29%2F%282%2A2%29+
x+=+%2815+%2B-+sqrt%28+225-128+%29%29%2F4+
x+=+%2815+%2B-+sqrt%28+97+%29%29%2F4+
x+=+%2815+%2B-+9.85%29%2F4+
solutions:
x+=+%2815+%2B+9.85%29%2F4+
x+=+24.85%2F4+
x+=+6.2125+
x+=+6.2+
or

x+=+5.15%2F4+
