Question

5. Factor each expression.
a. 15a - 13a
b. -6x – 18y
c. 36abc + 54ad​

Answer 1

Step-by-step explanation:

a.)

= 15a - 13a

= a(15 - 13)

= a(2)

= 2a

b.)

= -6x - 18y

= -(x + 3y)

c.)

= 36abc + 54ad

= 6a(6bc + 9d)

Answer 2

Answer:

$a \: ) \: \: 15a - 13a \\ = a(15 - 13) \\ = a(2) \\ = 2a$

$b) \: \: - 6x - 18y \\ = - 6(x + 3y)$

$c) \: \: 36abc + 54ad \\ = 9a(4bc + 6d)$
