Question

factorizar:
(5x-3)² - (6x+5)²
(16x-3)² - (12x+7)²
(7x-3)² - (10x+9)²
GRACIAS

Answer 1

Todas se hacen por Diferencia de Cuadrados:

(5x - 3)² - (6x + 5)² =
[ (5x - 3) + (6x + 5) ] [ (5x - 3) - (6x + 5) ]

(16x - 3)² - (12x + 7)² =
[ (16x - 3) + (12x + 7) ] [ (16x - 3) - (12x + 7) ]

(7x - 3)² - (10x + 9)² =
[ (7x - 3) + (10x + 9) ] [ (7x - 3) - (10x + 9) ]

Espero haberte ayudado, saludos!
