Answer 1

$hello \: friend...$

$= > m {}^{2} + 14m + 49 = 0$

$= > m {}^{2} + 7m + 7m + 49 = 0$

$= > m(m + 7) + 7(m + 7) = 0$

$= > (m + 7)(m + 7)$

$hope \: it \: helps \: you \: \\ please \: mark \: me \: as \: a \: brainlist...$

Answer 2

Answer:

m= -7

Step-by-step explanation:

m^2 + 7m + 7m +49 =0

m(m + 7) +7(m + 7) =0

(m +7)(m +7) =0

m + 7 =0

m =-7
