Answer :
Answer:
(9x + 15) = 3(3x + 5)
This is basically the distributive property of multiplication.
Step-by-step explanation:
We have to factorize the expression (9x + 15).
Now, 3 is the GCF of 9x and 15.
So, divide 9x by 3 and we will get [tex]\frac{9x}{3} = 3x[/tex] and divide 15 by 3 and we will get [tex]\frac{15}{3} = 5[/tex].
Now, sum the results as (3x + 5).
Then express the factorized term as the product of (3x + 5) and 3
i.e. (9x + 15) = 3(3x + 5)
So, this is basically the distributive property of multiplication. (Answer)
