What is the gcf of of -9y^2 + 6y

3y

Step-by-step explanation:

First find the factors of the terms.  You need to then figure out how many factors match.

-9y² = -1 · 3 · 3 · y · y

6y = 2 · 3 · y

3y is the greatest common factor.

the answe i =−n+5

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
