Answer 2

$25 {x}^{2} - 10x + 1 - 36 {y}^{2} \\ ( {5x)}^{2} - 2 \times 5x + 1 - ( {6y)}^{2} \\ ( {5x - 1)}^{2} - ( {6y)}^{2} \\ apply \: identity \: of \: square \: \\ difference \: \\ (5x - 1 + 6y)(5x - 1 - 6y)$
$18) {x}^{3} + ( {3)}^{3} \\ (x + 3)( {x}^{2} - 3x + 9)$
$19)54 {x}^{3} y - 128 {y}^{4} \\ 2y(27 {x}^{3} - 64 {y}^{3} ) \\ 2y(( {3x)}^{3} - ( {4y)}^{3} ) \\ apply \: identity \: {a}^{3} - {b}^{3} \\ 2y(3x - 4y)(9 {x}^{2} + 12xy + 16 {y}^{2} )$
