Question

Fatore os seguintes polinômios:
a) 44x + 66y – 55z
b) 8nx – 8ny
c) 4x – 8c + mx – 2mc
d) 81 – a 2
e) 36a2 + 24a + 4​

Answer 1

Resposta:

a) 44x + 66y – 55z

$11 \times (4x + 6y - 5z)$

b) 8nx – 8ny

$8n \times (x - y)$

c) 4x – 8c + mx – 2mc

$4 \times (x - 2c) + m \times (x - 2c)$

d) 81 – a 2

$(9 - a) \times (9 + a)$

e) 36a2 + 24a + 4

$4 \times (9 {a}^{2} + 6a + 1)$
