Question

(x+3).(x-5)=
(x+4).(x+6)=
(x-2).(x-3)=

Answer 1

(x+3).(x-5)= x² - 5x+3x - 15.: x² - 2x - 15
(x+4).(x+6)= x² + 6x + 4x + 24 .: x² + 10x + 24
(x-2).(x-3)= x² - 3x - 2x + 6 .: x² - 5x + 6

Answer 2

 Olá Luluica! :)


 ( x + 3 ) . ( x - 5 ) = x ² - 5 x + 3 x - 15 . : x ² - 2 x - 15

 ( x + 4 ) . ( x + 6 ) = x ² + 6 x + 4 x + 24 . : x ² + 10 x + 24

 ( x - 2 ) . ( x - 3 ) = x ² - 3 x - 2 x + 6 . : x ² - 5 x + 6


 Abraços! :)
