Answer 1

1. (x- 8) (x-8) = x²-8x-8x+64 = x²-16x+64

4. (4x + 3) (2x - 7) = 8x²-28x+6x-21 = 8x²-22x-21

7. (0, 2a + 8) (0,2 - 8) = 0.04a-1.5a+1.6-64 = -1.46a-62.4

2. (2a + 5) (2a - 5) = 4a²-10a+10a-25 = 4a²-25

5. (x+ 7) (x- 7) = x²-7x+7x-49 = x²-49

8. (a - 6) (a + 9) = a²+9a-6a-54 = a²+3q-54

3. (a - 3)2 = 4a-6

6. (2x - 3y) (2x - 3y) = 4x-6xy-6xy-9y² = 4x²-12xy-9y²

9. (9x - 4) (9x + 4) = 81x²+36x-36x-16 = 81x²-16
