Answer 2

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

(3y+2)(3y-2) = (3y)^2 - (2)^2 = 9y^2 - 4

(m-5n)(m+5n) = m^2 - (5n)^2 = m^2 - 25n^2

(x^2-2y)(x^2+y) = (x^2)^2 - (2y)^2 = x^4 - 4y^2

(6x-y)(6x+y) = (6x)^2 - (y)^2 = 36x^2 - y^2

(c^2-2d)(c^2+2d) = (c^2)^2 - (2d)^2 = c^4 - 4d^2

(6m-1)(6m+1) = (6m)^2 - (1)^2 = 36m^2 - 1
