Step-by-step explanation:
12m² - 7m + 1
= 12m² - 3m - 4m + 1
= 3m ( 4m - 1 ) - 1 ( 4m - 1 )
= ( 4m - 1 ) ( 3m - 1 )

GIVEN: 12m² - 7 m + 1
12m² - 7 m + 1 = 0
--> 12m² - 4m - 3m + 1 = 0
--> 4m(3m - 1) - 1(3m - 1) = 0
=> (4m-1) (3m-1) = 0
--> 4m-1 = 0, 3m-1 = 0
--> m = 1/4, m = 1/3
∴ The roots are 1/4 and 1/3
