m^2 -11m -60 = 0

m^2 -11m =60

(m^2 -11m + 121/4) = 361/4

(m – 11/2)^2 = 361/4

m – 11/2 = + or – 19/2

m = 11/2 + 19/2, 11/2 – 19/2

m = 15, -4

—————————————————

m^2 -11m -60

(11 +- Square root (121 +240))/2

11/2 +- 19/2

m= 15, -4

—————————————————-

m^2 -11m -60

(m – 15) (m + 4)

m = 15, -4
