Question

scrieti ca produs de 2 factori :
x²-a²=
x²-5²=
x²-3²=
1-4x²=
x²-1²

Answer 1

Doar aplici formula
$a^{2} - b^{2} =(a+b)(a-b)$

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)

Answer 2

( x - a )( x + a )

( x - 5 )( x + 5 )

( x - 3 )( x + 3 )

( 1 - 2x )( 1 + 2x )

( x - 1 )( x + 1 )
