Question

a) (x + 2).(x – 3) b) (x + y + 1).(x + 4) c) x.(x + y – 3) d) (x2 + 6).(x – 4)

Answer 1

Explicação passo-a-passo:

a). (x+2)×(x-3)

x² - 3x + 2x - 6

x² - x - 6

b). (x+y+1)×(x+4)

x² + 4x + yx + 4y + x + 4

x² + 5x + yx + 4

c). x . (x + y - 3)

x² + xy - 3x

d). (x² + 6)×(x - 4)

x³ - 4x² + 6x -24
