$\large\boxed{\bold{problema}}$

$(2m - 3) {}^{2} - (2m + 3)(2m - 3)$

$\large\boxed{\blue{Respuesta}}$

$-12m+18$

$\large\boxed{\red{solución}}$

$(2m-3) ^ { 2 } -(2m+3)(2m-3)$

$4m^{2}-12m+9-\left(2m+3\right)\left(2m-3\right)$

$4m^{2}-12m+9-\left(\left(2m\right)^{2}-9\right)$

$4m^{2}-12m+9-\left(2^{2}m^{2}-9\right)$

$4m^{2}-12m+9-\left(4m^{2}-9\right)$

$4m^{2}-12m+9-4m^{2}+9$

$-12m+9+9$

$\large\boxed{\green{-12m+18 }}$
