4m^224m+36=0

Ok, trent, so if solving for m use this formula: (Google quadratic formula to see formula) so, b should be 24, b^2 should be 24^2, a should be 4 and c should be 36. The answer should be m=3. But if you are to foil this, then 4m^224m+36 will be (4m12)(m3).

I would divide by 4 to get
m^2  6m + 9 = 0 , and now see it as a perfect square
(m3)^2 = 0
m3 = 0
m = 3
