Answer 1

Let's factor y2-4y+4

y2-4y+4

The middle number is 4 and the last number is 4.

Factoring means we want something like

(y+_)(y+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get 4

Multiply together to get 4

Can you think of the two numbers?

Try 2 and 2:

2+2 = 4

2*2 = 4

Fill in the blanks in

(y+_)(y+_)

with 2 and 2 to get...

(y+2)(y+2)

Answer:

(y-2)(y+2)
