You can put this solution on YOUR website!
Hint: We can write $\"16%5Ex%2B4%5E%28x%2B1%29-3=0\"$ as $\"%284%5Ex%29%5E2%2B4%2A4%5Ex-3=0\"$ . If we let $\"z=4%5Ex\"$ , then we get $\"z%5E2%2B4z-3=0\"$ . From here, solve for 'z'. Once you have solution(s) in terms of 'z', plug them into $\"z=4%5Ex\"$ to find solution(s) in terms of 'x' \n" ); document.write( "
