Answer 1

$\boxed{\boxed{\boxed{\bold{\red{solution :\longrightarrow}}}}}$

$\bold{ = 25 {a}^{2} - (4 {b}^{2} - 28bc + 49 {c}^{2} )} \\ \\ \bold{= {(5a})^{2} - [( {2b)}^{2} - 2.2b.7c + ( {7c)}^{2} ]}$

$\bold{ = {(5a)}^{2} - (2b - 7c) {}^{2} }\\ \\\bold{ = (5a + 2b - 7c)(5a - 2b + 7c)}$

$\boxed{\boxed{\boxed{\mathfrak{\green{I \: \: hope \: \: it \: \: will \: \: help \: \: you}}}}}$
