(5x-2y)(5x+2y) (2c-3a)(3a+2c) (10p-7q)(10p+7q) (8d+6c)(6c-8d)

Question

(5x-2y)(5x+2y)
(2c-3a)(3a+2c)
(10p-7q)(10p+7q)
(8d+6c)(6c-8d)

Answer 1

(5х-2у) (5х+2у) = 25х² - 4у²
(2с-3а) (3а+2с) = 4с² - 9а²
(10р-7q) (10p+7q) = 100p²-49q²
(8d+6c) (6c-8d) = 36c² - 64d²

Answer 2

25х²-4у² 4с²-9а² 100р²-49q² 36c²-64d²
