Answer 1

1. {x-5}{x+5}= x² - 25

2. {x+8}{x-8}= x² - 64

3. {3+x}{x-3}= x² - 9

4. {7+x}{7-x}= 49 - x²

5. {3x-5}{3x+5}= 9x² - 25

6. {7-2x}{7+2x}= 49 - 4x²

7. {6x-8}{8+6x}= 36x² - 64

8. {2+9x}{9x-2}= 81x² - 4

9. {2a+3b} [kwadratowe]= 4a² + 12ab + 9b²

10. {2a-5b}{2a+5b}= 4a² - 25b²

11. {4a-5b} [kwadratowe]= 16a² - 40ab + 25b²

12. {9a-7b}{9a+7b}= 81a² - 49b²

13. {2a+b} [kwadratowe]= 4a² + 4ab + b²

14. {6a-b}{b+6a}= 36a² - b²

15. {4a-3b} [kwadratowe]= 16a² - 24ab + 9b²

16. {7a+2b} [kwadratowe]= 49a² + 28ab + 4b²

Answer 2

1 (x-5)(x+5)=x^2+5x-5x+25=x^2+25

2 (x+8)(x-8)=x^2-8x+8x-64=x^2-64

3 (3+x)(x-3)=3x-9+x^2-3x=9-x^2

4 (7+x)(7-x)=49-7x+7x-x^2=49-x^2

5(3x-5)(3x+5)=9x^2+15x-15x-25=9x^2-25

6 (7-2x)(7+2x)=49+14x-14x-4x^2=49-4x^2

7(6x-8)(8+6x)=36x^2-64

8(2+9x)(9x-2)=81x^2-4

9=4a^2+12ab+9b^2

10=4a^2-25b^2

11=16a^2-40ab+25b^2

12=81a^2-49b^2

13=4a^2+4ab+b^2

14=36a^2-b^2

15=16a^2-24ab+9b^2

16=49a^2+28ab+4b^2
