You can put this solution on YOUR website!
Hint: If you let $\"z=x%5E2\"$ , then $\"z%5E2=x%5E4\"$ . So you can substitute 'z' for $\"x%5E2\"$ and $\"z%5E2\"$ for $\"x%5E4\"$ to get $\"6z%5E2-19z%2B15=0\"$ . From there, use the quadratic formula to find 'z'. Once you have solutions in terms of 'z', use the equation $\"z=x%5E2\"$ to find solutions in terms of 'x'. \n" ); document.write( "
