${x}^{2} + 2xy + {y}^{2} + 5x + 5y$
​

Answer 1

$a ) \: \: \: {x}^{2} - xy$

$b ) \: \: 2 {x}^{2} - 4x + 3xy - 6y$

$c ) \: \: {x}^{2} - 64$

$d ) \: \: \: {a}^{2} - {6}^{a} + 9$

$e ) \: \: 3 {x}^{2} - 15x$

$f ) 5 {a}^{2} - a \: + 10ab \: - 2b$

$g ) {x}^{2} + 40x + 400$

$9 {x}^{2} - 25$

${m}^{2} - {n}^{2}$

${x}^{2} + 2xy + {y}^{2} + 5x + 5y$
