Answer:

m = -3/2

Step-by-step explanation:

4m²+12m+9=0​   ...(i)

4 * 9 = 36

The factors of 36 are 1 , 36 ; 2 , 18 ; 3 , 12 ; 4 , 9 and 6 , 6.

6 + 6 = 12

So, equation (i) can be written as,

4m² + 6m + 6m + 9=0​

⇒ 2m ( 2m + 3) + 3(2m + 3) = 0

⇒ (2m + 3) (2m + 3) = 0

⇒ 2m + 3 = 0 or 2m + 3 = 0

m = -3/2
