Answer 1

Explicação passo-a-passo:

Resolução :

A) q² - 25 =

(q)² - (5)² =

(q+5).(q-5)

B) 33x +22y - 55z=

11.(3x + 2y - 5z)

C )x⁶+x⁷+x⁸

x^6(1 +x +x²)

D) 100 - y² =

(10)² - (y) ² =

(10+y).(10-y)

E)a² - 36=

(a)² - (6)² =

(a+6).(a-6)

F) 36cd +6cd² =

6cd.(6+d)

G) 4xy + 12xz=

4x.(y +3z)

H) 3/7 a - 3/7c=

3/7.(a - c)

I) 4a² - 9b² =

(2a)² - (3b)²=

(2a +3b).(2a - 3b)

J) 81a⁴ - y²z² =

(9a²)² - (yz)² =

(9a² + yz). (9a² - yz)
