You can put this solution on YOUR website!
Hint: If we let $\"z=x%5E%28-2%29\"$ , then $\"z%5E2=x%5E%28-4%29\"$ . Now apply the proper substitutions to get $\"2z%5E2-10z%2B2=0\"$ . Now use the quadratic formula to solve $\"2z%5E2-10z%2B2=0\"$ and get solutions in terms of 'z'. Once you have those solutions, plug them into $\"z=x%5E%28-2%29\"$ to find solutions in terms of 'x'. \n" ); document.write( "
