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

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.
