Question

1. (2× + 8) (4×-4)

2. (5× - 3) (6× + 6)

3. (× + 2) (× + 5)

4. (2y + 8) (6y - 4)

5. (5× + 4) (3× + 2)

6. (9× + 8) (3x - 4)




​

Answer 1

1. (2× + 8) (4×-4) = 8x²-1024

2. (5× - 3) (6× + 6) = 30x²-324

3. (× + 2) (× + 5) = x²-100

4. (2y + 8) (6y - 4) = 12y²-1024

5. (5× + 4) (3× + 2) = 15x²-16

6. (9× + 8) (3x - 4) = 27x²-1024
