Question

1. resolva as multiplicações
a) (x + 2).(x – 3) =

b) (2x + 5) . (x + 2) =

c) (3x – 2) . (2x – 2) =

d) X . (x – 4) =​

Answer 1

Resposta:

a) (x + 2).(x – 3) = x² - x - 6

b) (2x + 5) . (x + 2) = 2x² + 9x + 10

c) (3x – 2) . (2x – 2) = 6x² - 10x + 4

d) x . (x – 4) =​ x² - 4x

Espero ter ajudado, bons estudos!!
