Answer 1

^ inseamna la putere

Gen ^4 ridicat la puterea a 4

1 9-x^4

2. (x^2-9)(x^2+9) = x^4-81

3. (x^2+4)(x^2-4) = x^4-16

4. (16-x^2)(16+x^2) = 256-x^4

5. (3-a^2)(3+a^2)  = 9-a^4

6. (x^2-1)(x^2+1)(x^4+1)= (x^4-1)(x^4+1) = x^8-1

7. 81y^2+18xy+x^2

8. x^4+2x^2y^2+y^4

9. x^2+2x+1+x^2-2x = 2x^2+1

11. 4x^2-4V3x+3

12. x^2+8x+16

13. x^2+8x+16

14. x^3-x^2+x+x^2-x+1 = x^3+1
