a) X² - 8x = ____________________________________________

b) X² - x = ____________________________________________

c) 2x + 2y =____________________________________________

d) 3ª + 3b + 3c = ________________________________________

e) 15 + 3b + 5a + ab = ____________________________________

f) X² - 81 = ____________________________________________

g) X² + 10x + 25 = _______________________________________

h) X² - 8x + 16 = ________________________________________

i) X² + 15x + 36 = _______________________________________

Answer 1

Resposta:

Explicação passo-a-passo:

a) X² - 8x => x( x -8)

b) X² - x =>  x( x - 1)

c) 2x + 2y => 2( x + y)

d) 3ª + 3b + 3c => 3( a + b + c)

e) 15 + 3b + 5a + ab =>  ????

f) X² - 81 = (x - 9)(x + 9)

g) X² + 10x + 25 => (x + 5)²

h) X² - 8x + 16 => (x -4)²

i) X² + 15x + 36 => (x + 3) (x + 12)
