Factor completely the expression
5y2 + 15y
A
5(y2 + 3y)
B
y(5y + 15)
C
5y(y + 3)
D
20y3
Is the answer a b c or d
I agree, it is one of those. Which one do you think it is?
To factor completely the expression 5y^2 + 15y, you need to find the common factor that can be factored out from both terms.
Step 1: Determine the greatest common factor (GCF). In this case, the GCF is 5y since it is common to both terms.
Step 2: Divide each term by the GCF.
Dividing 5y^2 by 5y gives y, and dividing 15y by 5y gives 3.
Therefore, the factored form of the expression 5y^2 + 15y is 5y(y + 3).
Thus, the correct answer is C) 5y(y + 3).
