25m2 = 9
25m2 - 9 = 0
(5m)2 - (3)2 = 0 (like a2 - b2 = (a-b)*(a+b))
(5m - 3)*(5m + 3) = 0
Then m = 3/5 or -3/5
25m2 - 9 = 0
(5m)2 - (3)2 = 0 (like a2 - b2 = (a-b)*(a+b))
(5m - 3)*(5m + 3) = 0
Then m = 3/5 or -3/5

ANSWER
25m2=9
m2=±(9/25)
m= -3/5 or 3/5
Therefore the root of the equation is m=-3/5 or m=3/5.
