6m

Answer 1

55m I think,,,,,,,,,,

Answer 2

Answer:

Hence the value of  m = - 5 and - 8

Step-by-step explanation:

Here, the given number is

f (m) = m² + 13 m + 40

To find out the value of m, we need to apply middle term splitting method.

f (m) = m² + 13 m + 40

= m² + 8 m + 5 m + 40

= m ( m + 8) + 5 ( m + 8)

= ( m + 5) * ( m + 8)

( m + 5) * ( m + 8) = 0

m = - 5

m = - 8

Hence the value of  m = - 5 and - 8
