For the quadratic equation ((m^2 +1)x^2)-(2mx)+(m+1)=0, with roots x_1 and x_2,Find (x_1)^3 -(x_2)^3I solved it already so I can verify any answers/answer any questions
We derive the +- sign from the normal quadratic equation (as my teacher used it to solve the problem), and I'll try to give a more detailed explanation of the answer. Now that I see some of the mistakes my teacher made, I'll do the question again and find a more comprehensive answer.
This is the full answer to the question (I arrived at the same answer):
I used a way too long winded strategy that involved getting rid of and adding more square roots (hence why I used my teacher's strategy to post here)
Ans is in between of [0,4]
is it right??
