First check the equation you wrote - I think there's a typo. Then please post all your thoughts / working and tell us where you're stuck.

Also, please post questions in the maths forum in future and you'll get a faster response. I've moved this one for you
3. Can you? Surely if the equation is <0 it has no real roots?
