(X-10)(X+10)
(N-3)(N+3)
(8-y)(8+y)
(4x-1)(4x+1)
(10u+11)(10u-11)
(7s+3)(7s-3)

Answer 1

Son la identidad notable suma por diferencia (a+b) (a-b) = a² - b²

(x+1) (x-1) = x² - 1

(x+5) (x-5) = x²-25

(x-10) (x+10) = x²-100

(N-3) (N+3) = N²- 9

(8-y) (8+y) = 64 - y²

(4x -1) (4x +1) = 16x² - 1

(10u + 11) (10u - 11) = 100u² - 121

(7s + 3) (7s-3) = 49s² - 9
