Doar aplici formula
[tex] a^{2} - b^{2} =(a+b)(a-b)[/tex]
a) (x+a)(x-a)
b) (x+5)(x-5)
c) (x-3)(x+3)
d) (1-2x)(1+2x)
e) (x+1)(x-1)

( x - a )( x + a )
( x - 5 )( x + 5 )
( x - 3 )( x + 3 )
( 1 - 2x )( 1 + 2x )
( x - 1 )( x + 1 )
( x - 5 )( x + 5 )
( x - 3 )( x + 3 )
( 1 - 2x )( 1 + 2x )
( x - 1 )( x + 1 )
