Explicación paso a paso:

(4m + 3)(2m - 4) + 1 = 4(m + 1) ^{2}  + 3 \\ 4 {m}^{2}  - 8m + 6m - 12 + 1 = 4( {m}^{2}  + 2m + 1) + 3 \\ 4 {m}^{2}  - 2m - 11 = 4 {m}^{2}  + 8m + 4 + 3 \\ 4 {m}^{2}  - 2m - 11 = 4 {m}^{2}  + 8m + 7 \\ 4 {m}^{2}  - 4 {m}^{2}  - 2m - 8m = 7 + 11 \\  - 10m = 18 \\ m =  -  \frac{18}{10}  \\  \\ m =  -  \frac{9}{5}
