Given M=minim of sum of (x_k)^2 where x_k are roots of equation x^2+(m-2)x-(m+3)=0, then: a) k=1; b) k=2; c) k=9; d)k=6 ; e) k=1/2; f) k=8

The
answer provided by the problem needs to have a connection with the minimum value required,
hence, you should replace M for k. This assumption is made based on the logical reasoning
regarding the request of the problem and the information provided by the problem. The value of
k, cannot be larger than 2, since the quadratic equation cannot have more than 2 roots. You need
to evaluate the summation of the squares of roots of the given...
