Answer 1

(x+3)(x+6) = x² + 6 x + 3 x + 18 = x²+ 9 x + 18
(x+3)(x-6) = x² -6 x. +3x. -18. = x² -3x-18
(x-3)(x+6)= x² -3x+6x -18. = x² +3x -18
(x-3)(x-6) = x² -6x-3x+18. =x²-9x+18
(x-2)(x-2) = (x-2)² = x²-4x+4
(x+7)(x+7) = x²+ 14x +49

(2x+3y)(2x+3y) = 4x² +9y²+12xy
(x+2)(x+2). = x²+4x+4
(3a+1)(3a+1) = 9a² +6a +1
(1001)(1001) = (1000+1)(1000+1)
= (1000+1)² =1000²+1+2000
=1000000+2000+1
=1002001
