Question

Factorise: 3m² +6+ 19m

Answer 1

Answer:

9m square + 6 +19 m = 28 m + 6

Answer 2

Answer:

=> m = -1 or m = -2

Step-by-step explanation:

Given that:-

$3 \mathrm{~m}^{2}+6+ 9 \mathrm{~m}=0$

As we have to factorize the equation:

Now rearrange the terms, we get

=> $3 \mathrm{~m}^{2}+9 \mathrm{~m}+6=0$

By splitting the terms,

=> $3 \mathrm{~m}^{2}+3 \mathrm{~m}+6 \mathrm{~m}+6=0$

By further calculation, we get

=> $3 \mathrm{~m}(\mathrm{~m}+1)+6(\mathrm{~m}+1)=0$

=> ( m + 1 ) ( 3m + 6 ) = 0

=> m + 1 = 0 or 3m + 6 = 0

=> $\mathrm{m}=-1 \text { or } \mathrm{m}=\frac{-6}{3}=-2$

=> $\mathrm{m}=-1 \text { or }-2$

Hence, the required solution is -1 or -2.
