You can put this solution on YOUR website!
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. \n" ); document.write( "
