Answer 2

Let's factor y2+24y+144

y2+24y+144

The middle number is 24 and the last number is 144.


Factoring means we want something like

(y+_)(y+_)

Which numbers go in the blanks?


We need two numbers that...

Add together to get 24Multiply together to get 144

Can you think of the two numbers?


Try 12 and 12:

12+12 = 2412*12 = 144

Fill in the blanks in
(y+_)(y+_)
with 12 and 12 to get...

(y+12)(y+12)


Answer:

(y+12)(y+12)
