Question

A)(x+5).(x+2)
B)(3x+2).(2x+1)
C)(x+7).(x-4)
D)(3X+1).(3X-1)

ME AJUDEM POR FAVOR

Answer 1

A) (X + 5 ) (X + 2 ) = X² + 2 X + 5 X + 10 = X² + 7 X + 10

B)(3 X + 2 ) (2 X + 1 ) = 6 X² + 3 X + 4 X + 2 = 6 X² + 7 X + 2

C)(X + 7 ) (X - 4 ) = X² - 4 X + 7 X - 28 = X² + 3 X - 28

D)(3 X + 1 ) ( 3 X - 1 ) = 9 X² - 1
