Answer 1

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

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

(x+4)^2 = x ^2+8x+ 16

(p+5q)^2 = p^2+10pq+ 25q ^2

(5x+3y) ^2 = 25x^2+30xy+9y^2

(x-2) (x+1) = x^2 - x - 2

(4x+2) (x-5) = -16x-8

(a+3) (a-3) = a^2 -9

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

(3x+2)^2= 9x^2+12x +4

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

(a-3b)^2= a^2-6ab+9b^2

(a+3) (a-2) = a^2+a -6

(2x-5) (2x+5) = 4x^2-25

(5x-2) (5x+2) = 25x^2-4

(a+1)^2 = a^2+2a+1

(x-5) ^2 = x^2- 10x + 25

(6-x) ^2= x^2-12x+ 36

(2a-3) (a+3) = 2a^2 +3a -9

Espero te sirva :D
