AYUDAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA​

Answer 1

Respuesta:

Explicación paso a paso:

a)

• ac + ad - 2bc - 2bd =

a.(c+d) - 2b.(c+d) =

(a - 2b) . ( c + d)

• 2c² + 4cd + 2d² =

2.(c² + 2cd + d²) =

2 . (c+d)²

MCD = (c+d)

MCM = 2 . (c+d)² . (a-2b)

2)

• 9x³ + 27x² - 4x - 12 =

9x².(x + 3) - 4.(x + 3) =

(9x² - 4) . (x+3) =

(3x + 2).(3x-2).(x+3)

• x² + 6x + 9 =

(x + 3)²

MCD = (x+3)

MCM = (3x + 2).(3x-2).(x+3)²
