ill just demonstrate the solution for you,
m^2 +12m = 3
m^2 + 12m + 36 = 3 + 36
(m + 6)^2 = 39
get the square root of both sides, then it will become
m +6 = square root of 39
m = -6 square root of 39
m² + 12m + (12/2)² = 3 + (12/2)²
m² + 12 m + (6)² = 3 + (6)²
m² + 12m + 36 = 3 + 36
(m + 6)² = 39
[tex] \sqrt{(m+6) ^{2} } = \sqrt{39} [/tex]
[tex]m+6 = + or - \sqrt{39} [/tex]

[tex]m = -6- \sqrt{39} [/tex]   or
[tex]m = -6 + \sqrt{39} [/tex]
