Question

c) (6y² + 7y) . (6y² – 7y)


d) (a²/2 – 5) . (a²/2 + 5)


e) (0,5x + 2) . (0,5x – 2)


f) (x + 3y/2) . (x - 3y/2)

Answer 1

Resposta:

Explicação passo a passo:

C) (6y² + 7y) . (6y² – 7y)

= (6y^2)^2 - (7y)^2

= 36y^4 - 49y^2

_________________

d) (a²/2 – 5) . (a²/2 + 5)

= (a^2 / 2)^2 - 5^2

= a^4 / 4 - 25

________________

e) (0,5x + 2) . (0,5x – 2)

= (0,5x)^2 - 2^2

= 0,25x^2 - 4

_________________

f) (x + 3y/2) . (x - 3y/2)

= X^2 - (3y/2)^2

= X^2 - 9y^2 /4
