"solve each equation. check the solutions. 49m squared - 126m + 81 = 0"

49m^2 - 126m + 81 = 0
(7m - 9)(7m - 9) = 0 {factored the perfect square trinomial into two binomials}
7m - 9 = 0 {normally, you would set each factor equal to 0, but here, they are the same}
7m = 9 {added 9 to both sides}
m = 9/7 {divided both sides by 7}
