%282x+%2B+1%2F3%29%2A%285x+-+2%2F3%29+

I recommend that you FOIL it out. Do you know about FOIL?
F= First times First
O= Outer times Outer
I = Inner times Inner
L = Last times Last

%282x+%2B+1%2F3%29%2A%285x+-+2%2F3%29
F = 2x%2A5x+=+10x%5E2
O = 2x%2A+%28-2%2F3%29+=+%28-4x%29%2F3%29
I = 5x%2A%281%2F3%29+=+%285x%29%2F3
L= %281%2F3%29%2A%28-2%2F3%29+=+-2%2F9

Total: 10x%5E2+-%284x%29%2F3+%2B+%285x%29%2F3+-+2%2F9+

Combine like terms:

Total: 10x%5E2+%2Bx%2F3+-+2%2F9+
