following the values of parametric m ,solve and discuss in R the following equations , where x is unknown :
1)x^2+(m-1)x-m=0
2)3x^2-13mx+10m^2=0
3)(m-4)x^2-2(m-l)x+m+1=0

These are all Quadratic Equations. Have you tried the Quadratic Formula?Quote:

yeah i know the formula , but not with parameter m , when m is known
This is, after all, algebra! You are allowed to replace numbers with letters. Use the quadratic formula with, for the first example, a= 1, b= m-1, c= -m.
