question 28
factor completely. if the polynomial is prime, say so.
15y² - 18y
○ 3y(5y - 6)
○ 3y(5y + 6)
○ y(15y - 18)
○ -3y(5y + 6)

Explanation:

Step1: Find GCF of terms

The terms are \(15y^2\) and \(-18y\). GCF of 15 and 18 is 3, GCF of \(y^2\) and \(y\) is \(y\). So GCF is \(3y\).

Step2: Factor out GCF

Factor \(3y\) from \(15y^2 - 18y\): \(3y(5y - 6)\) (since \(3y\times5y = 15y^2\) and \(3y\times(-6)= -18y\)).

Answer:

A. \(3y(5y - 6)\)
