Hi,

Solve  (Set to ZERO)

-9x(x-1)=2

 -9x^2 + 9x - 2 = 0

 9x^2 - 9x + 2 = 0

x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+

x+=+%289+%2B-+sqrt%28+81-72%29%29%2F%2818%29+

x+=+%289+%2B-+sqrt%28+9%29%29%2F%2818%29+

x+=+%289+%2B-+3%29%2F%2818%29+

   x = 12/18 = 2/3  0r  x = 6/18 = 1/3

 x is  1/3,  2/3
