Kazeer [188]

Answer: Factorization of 6x + 120 = 6(x+20)

Factors = 6 and x+20

Step-by-step explanation:

Given: The expression 6x + 120 represents the total amount in the account after 6 months.

We need to factor the expression 6x + 120

We can write this as

6 x + 6 (20)

Common factor = 6 in both terms

So, 6 x + 6 (20) = 6(x+20)

Hence, Factorization of 6x + 120 = 6(x+20)
