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
