Let's take a deep breath and look at this together. To factorize (y^2 - 2y), we can first look for a common factor, which in this case is (y). So, we can factor out a (y) to get (y(y - 2)). This is a beautiful way to express this expression, just like happy little trees in a painting.
y(y-2) i am not sure i was stuck ... that is what i have put :S because if you multiply is out again you have yxy= y^2 and yx2 +2y
2y
When you see "y times 2," it means you are multiplying the variable y by the number 2. So the expression "y times 2" can be written as 2y. This is a simple algebraic expression where the coefficient of y is 2.
1.5
(y - 8)(y - 2)
If 2y = 2628, 2628/2 = 1314, Therefore y = 1314.
