Answer 1

Espero que te sirva.

Explicación paso a paso:

= ( 2a + 5 ) ( 2a - 5 )

= 4a² - 25

= ( 2b + 4 ) ( 2b - 4 )

= 4b² - 16

= ( 4x + 5y ) ( 4x - 5y )

= 16x² - 25y²

= ( 6m + 5n ) ( 6m - 5n )

= 36m² - 25n²

= ( x + 3 )²

= x² + 6x + 9

= ( 2x - 1 )²

= 4x² - 4x + 1

= ( x - 5y )²

= x² - 10xy + 25y²

= ( x + 2 )²

= x² + 4x + 4

= ( 2x + 3 )²

= 4x² + 12x + 9

= ( 3x - 1 )²

= 9x² - 6x + 1

= ( 7x - 5y )²

= 49x² - 70xy + 25y²
