Answers 1. 3x(4xy) = 12x2y 2. 3x(x + 5) = 3x2 + 15x 3. 5xy(3x + 2) = 15x2y +10xy 4. (x + 2)(x – 2) = x2 - 4 5. (x + 3)2 = x2 + 6x + 9 6. (x + 5)(x + 3) = x2 + 8x + 15 7. (x – 7)(x + 2) = x2 – 5x – 14 8. (x – 3)(x – 4) = x2 – 7x + 12 Click for more answers

Answers 9. (2x + 3)(x – 4) = 2x2 - 5x - 12 10. (3x + 2)(4x – 1) = 12x2 +5x - 2 11. (3x + y)(2x – 5y) = 6x2–13xy-5y2

12. (2x - 4y)(2x + 4y) = 4x2 – 16y2

13. 4x2(6xy) = 24x3y 14. 5x2(7x – 2y) = 35x3 – 10x2y 15. (3x2 + 4)(2x2 – 5) = 6x4 – 7x2 -20
