Answer:

${ \tt{16 {b}^(2) c {}^(12) - 0.25 }}$

» Change the decimal to a fraction:

$= { \tt{ {16b}^(2) {c}^(12) - (1)/(4) }} \\$

» Change the other degrees to indices;

$= { \tt{ \blue{( {4}^(2)) }} {b}^(2) {c}^(12) - \frac{1}{ \red{( {2}^(2) )}} } \\ \\ = { \tt{ {(4bc {}^(6) )}^(2) - (1)/(4) }}$

» Factorize:

$= { \tt{4}^(2) \{ ( {bc}^(6) ) {}^(2) - (1)/(4) \}} \\ \\ { \boxed{ \tt{ = 16 \{ { \blue{{(bc}^(6)) {}^(2) - (1)/(4) } \}}}}}$
