- (3+2√5)²=

- (x - 2√3)²=

- (√5 + 2√6)²=

- (3ab + ½)²=

- (2x - 3yz)²=

- (5x - y³)²=

- (2x - ¾)²=

- (1,5 - 2a)²=

- (3z⁵ - 6)²=

- (4ab + 2)²=

- (⅓a +¾)²=

- (x - 3y²)²=

Answer 1

- (2 √2 + √8)²= 8 + 16 + 8 = 32

- (3+2√5)²= 9 + 12√5 + 20 = 29 + 12√5

- (x - 2√3)²= x² - 4√3x + 12

- (√5 + 2√6)²= 5 + 4√30

- (3ab + ½)²= 9a²b² + 3ab + 1/4

- (2x - 3yz)²= 4x² - 12xyz + 9y²z²

- (5x - y³)²= 25x² - 10xy³ + y^6

- (2x - ¾)²= 4x² - 3x + 9/16

- (1,5 - 2a)²= 2,25 - 6a + 4a²

- (3z⁵ - 6)²= 9z^10 - 36z^5 + 36

- (4ab + 2)²= 16a²b² + 16ab + 4

- (⅓a +¾)²= 1/9a² + 1/2a + 9/16

- (x - 3y²)²=x² - 6xy² + 9y^4

 

Answer 2

8+8=16

9+20=29

xkwadrat +20=20 +xkwadrat

5+24=29

9ab +0,25

4x - 9yz

25x - y do szóstej

4x 9/16= 36/16=9/4

1,25 -4a kwadrat

9z do dzesiątej - 36

16ab kwadrat + 4

1/9a kwadrat + 9/16

x kwadrat - y do czwartej
