Question

1) Fatore x² − 9.

2) Fatore x³ − 27.

3) Fatore x²− 12x+ 36.

4) Fatore ax+ bx − ay − by

5) Fatore x²− 10x+ 16.
​

Answer 1

Resposta:

X²= -9= 0

X²= 9

X= √9

= 3

x³ − 27.

X³ – 27= 0

X³ = 27

X= √27

X= 9

x²− 12x+ 36

(x - 6) . (x - 6)

=> (x - 6)²

ax + bx - ay - by

a(x + y) - b(x + y)

(a - b). (x + y)

=(a - b) . ( x + y)

x²− 10x+ 16.

(x+2) . (x+8)
