Folosim proprietatea

$x {}^{2} - y { }^{2} = (x - y)(x + y)$

(5m-1)(5m+1)

(7/5-a)(7/5+a)

(13/5x-2z)(13/5+2z)

(2/3x-3/10y)(2/3x+3/10y)

$(\sqrt{7} - x)( \sqrt[]{7} + x)$

$(4x {}^{2} - 9y {}^{2} )(4x {}^{2} + 9y {}^{2} )$

$(4a {}^{2} - 3)(4a {}^{2} + 3)$

$(9x {}^{2} - 5)(9x {}^{2} + 5)$

$(9m {}^{4} - 4)(9m {}^{4} + 4)$
