Answer 1

Resposta:

a) (x + 4) x (x + 4) =  x elevado a 2 + 4x + 4x + 16= x elevado a 2 + 8x + 16

b) ( x + 5 ) x ( x + 5 ) = x elevado a 2 + 5x + 5x + 25 = x elevado a 2 + 10 x + 25

c) ( x + 10 ) x ( x + 10 ) = x elevado a 2 + 10x + 10x + 100 = x elevado a 2 + 20x + 100

d)( y + 2 ) x (y + 2 ) = y elevado a 2 + 2y + 2y + 4 = y elevado a 2 + 4y + 4

e) (y + 7 ) x (y + 7 )= y elevado a 2 + 7y + 7y + 49 = y elevado a 2 14 y + 49

f)( x + 12) x ( x + 12 )= x elevado a 2 + 12x + 12x + 24 = x elevado a 2 + 24x + 24

h) ( 2x + 4 ) x ( 2x + 4)=  4x elevado a 2 + 8x + 8x + 16 = 4x elevado 2 + 16x + 16

i) (3x + 5 ) x ( 3x + 5 ) = 9x elevado a 2 + 15x + 15x + 25 = 9x elevado a 2 + 30x + 25

j) ( 9x + 3 ) x ( 9x + 3 )= 81x elevado a 2 + 27x + 27x + 9 = 81x elevado a 2 + 54x + 9

k) ( 4x + 1 ) x (4x + 1 )=  16x elevado a 2 + 4x + 4x + 1 = 16x elevad0 a 2 + 16x +
