a) (x + 8)2 =

b) (3x – 4)2 =

c) (2x – 6)2 =

d) (2x – 9) (2x + 9)=

e) (4b – 6)2 =

f) (7c + 4)2 = 
g) (4x + 11) (4x- 11) =

h) (7x – 10)2 =​​

Answer 1

Precisaremos aplicar a distributiva:

a) (x + 8)2 =

2x + 16

b) (3x – 4)2 =

6x - 8

c) (2x – 6)2 =

4x - 12

d) (2x – 9) (2x + 9)=

4x² + 18x - 18x + 81

e) (4b – 6)2 =

8b - 12

f) (7c + 4)2 =  

14c + 8

g) (4x + 11) (4x- 11) =

16x² - 44x + 44x - 121

h) (7x – 10)2 =​​

14x - 20
