Question

Fatore as expressões a seguir: Se explicarem agradeço :)

5xy + 5x + 3y + 3 =

mx² - my² - nx² +ny² =

a³ - a² + ab² - b² =

8cx - 12cy + 2dx - 3dy =

2a³ + 2a²b + 2a² - 3a - 3b - 3 =

bm + mn + ab + an =

Answer 1

5xy + 5x + 3y + 3 = 5xy + 3y + 5x + 3 ==> y(5x+3)+ 1(5x+3)==> (5x+3)(y+1)

mx² - my² - nx² +ny² = m(x² - y²) - n(x² - y²)==>(x² - y²)(m - n)

a³ - a² + ab² - b² = a³ + ab² - a² - b² => -a(- a² - ab²) - (a² - b²)==> (- a² - b²)(-a - 1)

8cx - 12cy + 2dx - 3dy = 4c(2x-3y) +d(2x-3y)==> (2x-3y)(4c+d)

2a³ + 2a²b + 2a² - 3a - 3b - 3 =

bm + mn + ab + an =
