Do we really have to go through that lengthy procedure?
1) (3r + 2 - s)(4r+ 9 - s) = 0
->s = 3r+2 or s= 4r+9
2) (4r - 6 - s) 93r + 2 - s) = 0
s= 3r+2 or s= 4r-6
s has a common value s= 3r+2
I understand how you got s = 3r + 2.. but what I dont understand is that why having 3r + 2 in both the equations makes the answer C..
