m is 4 and 12.
Note, since y2 is tangent to y1, so there is only one point of intersection for these two lines. Meaning which there only one root for these two equation, so b2-4ac must equal to zero.
Additional note: if these two lines does not intersect each other, b2-4ac is small than zero.
If these two lines intersect at two point, b2-4ac is bigger than zero.
Enjoy study.
