Explanation / Answer

( 3x - 8 ) ( 3x + 8)

applying product formula to multiply

3x * 3x + 3x * 8 - 8* 3x - 8*8

9x^2 + 24x - 24x - 64

9x^2 - 64

2) ( x+2 ) (6 x^2 -x + 1 )

x* 6x - x*x + x*1 + 2* 6x^2 - 2*x + 2* 1

6x^2 - x^2 + x + 12x^2 - 2x + 2

17x^2 - x + 2

3) ( A+B)^2 = A^2 + 2AB+ B^2

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

= 16x^2 + 32x + 4
