Answer:
y = 0 and y = -1/3
Explanation:
y2-6y = 0
You can rewrite it as 2y -6y=0 for easier look,
Take the common factor here is 2y out, we will get:
2y*(1-3y) = 0
We learn that a*b=0 when a=0 or/and b=0 so in this case,
2y*(1-3y) = 0
2 options:
2y = 0
y = 0
and
1-3y = 0
-3y = 1
y = -1/3
Hope this help you :3
