Answer:

9/11

Step-by-step explanation:

m-1/m = 4

m-1/m = 4m-1=4m

m-1/m = 4m-1=4mm -4m = 1

m-1/m = 4m-1=4mm -4m = 1-3m = 1

m-1/m = 4m-1=4mm -4m = 1-3m = 1m = -1/3

m-1/m = 4m-1=4mm -4m = 1-3m = 1m = -1/3then,

m-1/m = 4m-1=4mm -4m = 1-3m = 1m = -1/3then, 3m/m^2 + m - 1

3(-1/3) / (-1/3)^2 +(-1/3) - 1

= -1 / 1/9-1/3-1

= -1 / (1-3-9) / 9

= -1 / -11 / 9

= -9 / -11

= 9/11
