This doesn't look right, but here goes anyway. Take out the lowest power of the factor, which in this case is x%5E%28-4%2F7%29. Next you will have to subtract exponents:
9x%5E%282%2F7%29+-+5x%5E%28-4%2F7%29+
x%5E%28-4%2F7%29+%289x%5E%28%282%2F7%29-%28-4%2F7%29%29+-+5%29
x%5E%28-4%2F7%29+%289x%5E%286%2F7%29+-+5%29
