Remember that you CANNOT divide by zero. So set the denominator 7w%2B8 equal to zero to get 7w%2B8=0. Solve for 'w' to get w=-8%2F7. So when w=-8%2F7, the denominator is equal to zero which is what we don't want. This means that we must make the restriction that w%3C%3E-8%2F7 for the expression %285w-6%29%2F%287w%2B8%29 to make sense.
